Fight monetary inflation? Not really! Your shrunken 25 cents now have a value of 15$ !! This principle as when a government start to print too much money or like criminals are making a lot of counterfeit money... The result is more money in circulation... So yeah, this is creating more inflation! Just imagine if everybody was shrinking and selling all their coins for 75 times their original value... Would we all get rich? BTW... I know you was joking, but you are still WRONG!!! lol
The crazy part is, that this is the result of relativistic length contraction of the distances between the electrons in the coin. They are forced into the center by the eddy current.
woah!!! that was GREAT!!! its true, reality is far more interesting than fiction any day...i wonder how big this could scale up...maybe shrink a gun,or maybe a neodymium super magnet (n 52?) i feel its the extreme experiments we will learn something new from...out of the box thinking ...keep up the good work...and even the bizarre ,seemingly crazy experiments!!! thank you : )

Apparently the iron in the hemoglobin cells in blood is in a form that is actually repelled by a magnet. A strong enough electromagnet, and you can levitate said frog.
That was my question. I think the clearest answer is provided here: en.wikipedia.org/wiki/Magnetic_levitation#Direct_diamagnetic_levitation EDIT: I guess the easiest way to explain it intuitively is by thinking of a frog as an animal composed of mostly water. Each water molecule can become a small magnet (facing the opposite direction of the magnetic provided magnetic field) when under the force of a strong magnetic field.
Water is diamagnetic (from Wiki: diamagnetic materials create an induced magnetic field in a direction opposite to an externally applied magnetic field, and are repelled by the applied magnetic fiel, frogs have a considerable amount of water in them...therefore floating frogs :)
geocarey I'd guess either 1. we are way to big 2. the MRI isn't quite powerful enough (they only go up to about 3T as opposed to like 15T or more for superconducting magnets) or 3. the magnets are more or less on all sides so the forces cancel out, though, these are all just educated guesses.
+anvil777 One and two. Three would actually allow you to float given one and two (size and magnetic field) were factored in. if you did not have an even enough magnetic field, you would likely be pushed out where it is weakest.
Interesting demonstration on an applicable use of High voltage! The electromagnetic force inside that work coil is enough to compromise the structural integrity of both the coin and coil - science at work!
Does the quarter still weigh the same? Meaning, it is now smaller but more dense? If it lost weight, what bit is gone and where did it go? Great video as always! TY.
For the most part, still weighs the same. It might lose a tiny bit of mass just by the explosions and pieces being scraped off, but it just becomes fatter as you can see in the extreme case at 1:52
I also thought about that! I think it still weights the same. Although as the coin gets really hot metal from the surface can evaporate we cannot see any signs of oxidation on coin. But I could be wrong.
We weighed coins before and after and they were identical, to the margin of error of the jeweler's scale. (~10 mg) The coins are amazingly unscathed, considering the induced current levels in them. I would have expected at least some vaporization or melting of metal from the coins but the wooden or acrylic dowels we used never showed any obvious residue from the coins. There was a lot of vaporized copper everywhere though. FYI, we did calculations of the speed of the wire fragments in the high speed footage and the copper coil is exploding at roughly mach 3.
www.usmint.gov/consumer/?action=FAQ , read that and tell me what it says about people or companies changing currency. Also keep in mind that those laws were written under the gold standard era of coinage. It is only illegal to alter coins for fraud, such as chaining the weight bullion to make it lighter than the stamped weight, or to melt coins in current circulation to gain money from their face value versus their metallic value (i.e. like 1980's and before all copper pennies being melted for scrap is illegal since they are in circulation, while you can melt pre-1964 quarters which are + 90% silver by weight since they are out of circulation). It is also illegal to modify currency like quarters by putting holes in them for the purpose of defrauding things like vending machines, while not for jewelry. Destroying currency is not illegal as long as it is not for fraudulent purposes.
the interesting thing is, not a lot really. you charge the capacitor using low current, high voltage. i dont know how many amps they pull from the wall, but if its a standard 110 outlet, the maximum would be around 15amp, and only for the time needed to charge the capacitor. thats whats great about caps. you can charge them with very low current and high voltage slowly, then in a blink of an eye dump all that energy, creating massive amounts of current output. thats how theyre getting something like 50kamp(?) and millions of watts (for literally fractions of a second) out of a power supply (the wall) that cant push more than 1500w or so. basically, it probably doesnt cost all that much at all. a few cents maybe.
+m4xwellmurd3r forgot to mention, if they were to push 1000w from the wall through the transformer to charge the capacitor, they would be charging it at a rate of 125mah or so. very low current (since when you step voltage up current drops)
physics girl is a bit off centre. The time span is so small, the power needs to be put in context. Its the energy, not that power, that crushes the coin.
Hussam Kazah it would be cold worked, so yes slightly stronger in most cases, assuming it did not get so hot as to temper it. Coins are made from cold worked material already though and there is a limit to how much it can add. I would guess the coins are half as hard as they could be from working, before being shrunk.
The shrinking happens on that one plane so it would probably form a sort of cylinder with rounded tops and fatter near the middle, or fold based upon where the imperfections are.
To follow up this point: shrinking happens along the plane in part because the magnetic field lines are only along that direction. If we think of another system (helmholtz coils in multiple directions -- en.wikipedia.org/wiki/Helmholtz_coil), then we might be able to get shrinking along multiple directions... In essence turning the sphere into a cube! (maybe) I think more thought needs to go into how that would be done. I suppose if magnetic monopoles existed, we could imagine shrinking of a hollow sphere, but I am not sure how everything works out there...
Thanks Firaro and LeiosOS -- I was thinking that the solid sphere might end up as sort of an hourglass shape or as you said a cylinder with rounded ends. The hollow sphere would probably just explode or maybe just be quite deformed.
A sphere would shrink about the circumference in the plane of the coil, and sort of squirt out along the poles. A sphere with a small hollow would probably close up, while a large hollow would probably be split, similar to the can demonstration.
Keep in mind that Dr. Brown is pronouncing gigawatt as "jigawatt". (And, many people think 'jigawatt' is the correct pronunciation... However, since the prefix giga is of Greek origin, I believe that giga should be pronounced with a hard 'g'.)

I'm literally learning about this stuff in magnetism in school right now and I NEVER thought it could be this cool. Looking at how these forces and laws actually work in real life makes me want to go back and learn about them, something that hours and hours of theoretical teaching could never do. Thank you for making this video!!
So it's a 1/8th now. Hmm, seriously though, is this similar to the effect inside a black hole, which ends up with a super heavy dwarf star at it's center??
I think it's the other way around. A black hole just has a point of insane mass at its center. once, it may have been a super heavy star, before its super nova.
Yes. The matter in the center of a black hole gets shrunk when passing through, and this process creates exotic particles and a giant electromagnetic field. The difference is, black holes have enough material so as to not overload their total energy capacity, whereas with this experiment, they oversaturated the copper and coin's ability to stay stable during such a massive voltage drop, causing it to explode. It's the same as trying to force 1000 gallons of water per minute through a tube only capable of 100 gallons per minute; the tube will definitely explode if you try it.
@@wordreet Yes, matter does pass through a black hole. At that point, any solid matter would be shredded into its base waveform/particles, resulting in pure energy, and as we know a moving energy source creates a magnetic field, hence the giant magnetic fields surrounding black holes. The alternative explanation can be thrown out the window, since they literally claim the laws of physics break down when black holes are concerned.
wow i just found your channel and am totally in love ! Subscribed ! I love the topics you choose and most of all - the presentation. Keep up the amazing work ! :D
@ about 1:40 she shows a side view of some very deformed coins and says something like it only shrinks from the sides but bulges out the middle. I imagine the volume would stay about the same. If not there would either be a mass or density change. Perhaps with all the deformation and heat some of the material sometimes gets blasted off. In that case only would it weigh less.
@@mattsowerbutts4163 There are no molecules in coins. Only metal atoms with a network metallic bonds between them. I don’t know if the electricity can change the length of those bonds, but there are no separate molecules to squeeze together.
You can wrap the outside of that coil with a magnetic sleeve, and effectively 'push' the outer bands of EM force inward, doubling the power in that work area. Just so ya know.
Great video and topic, thank you. Perhaps I missed it but shouldn’t it be explained that the rapid power input to the coin presumably also heats it towards its melting temperature which facilitates its deformation in compliance with the electromagnetic forces…?
I thought I heard somewhere that if there were to be a tiny black hole it would be extremely powerful until it eventuallly grew and consumes the earth and all that surrounded it
The serious academic physicists that I've heard have indicated otherwise. For example, when there was some pop-hysteria about the possibility of the LHC creating a black hole with its high-energy collisions (up to 13 teravolts!), the physicists did the calculations and pointed out: "Um, even if it did, they would be so tiny that they would evaporate before they could affect anything else." A black hole a kilometer across would definitely rip the earth up. However, it would have a mass something like 10% of the entire sun (which is a million miles across), and it would probably last longer than the current age of the universe. However, a black hole the mass of a single coin would come and go in a flash before it could do anything meaningful. It's an exponential scale both ways: big = lasts super long, but small = disappears super fast. You can apply the "Nature abhors a vacuum" principle. A big vacuum (a big black hole) sucks up a lot of nature faster than it can be evaporated, so it maintains itself; but a small black hole gets sucked out of existence by nature almost immediately.
Sorry for bringing up a dead thread, but if you watched Kurzegaht's video on coin-sized black holes, then you would know that the coin black hole will explode with a higher power than Hiroshima, so maybe it won't be harmless.
Thanks for joining in -- new thoughts are always welcome :) You bring up a fair idea, but in the case we were discussing, it was not a black hole the SIZE of a coin, but a black hole with the MASS of a coin (a couple grams). There is a vast, vast difference between the two. A black hole the SIZE of a coin would have the mass of a mountain range, and yes that would be bad if it formed on earth! Likewise, if the LHC had managed to cause microscopic black holes with their particle collisions, those would have had the mass of a few protons and evaporated away instantly, with no effective gravity to pull in anything from the surrounding area. At that scale, gravity is so weak as to be meaningless compared to chemical bonds and other factors, and so a mosquito with billions of particles in it can just hang on the ceiling because of a little surface tension. When we start looking at things like black holes, the exponential differences in size, mass, gravity, and time get so extreme that it is easy to be misled by our everyday intuitions. We get into the realm of comparing infinities and inverse-infinities, and our brains are not naturally wired to do that. Intuitively, we are used to comparing feathers to rocks, maybe, but the relative differences in these cosmic events are many orders of magnitude more different from each other. I hope that helps...
Very cool. But, what happens to the structure of the coin? The mass must remain the same because you're not removing any from the shrunken coin. Is it imploding under the forces? Much the same as imploding the nuclear material of a fission bomb to create critical mass? So, the coin will weigh the same in both forms, but the internal structure will become more dense?
Did I see a comment along the lines of a "waste of electricity"? Well, let's see: At a rate of $0.1 pew kW-hr, that's 26,496,000W x 30uS, or 26496kW x $8.3ee -9 = 0.002 cents- two milli-cents per shrink or 500 coin shrinks for a penny. Plus It's legal as long as you you don't sell the quarter for more than 25 cents, just add a working (?) fee. I have been into this for a while, and am working on a "re-usable coil" with a very uniform shrink (% per kl). And, yes, the mass remains constant. atta-Girl! --dalE
I thought you must have made a mistake, but no, I guess it's hard to judge how long a microsecond really is, because it really adds up to 2,2 millicents for 0,22 watthours... Amazing.
Yea the main question as stated below is "Will this cause the mass of the coin to become more dense" If it does the applications would be extraordinary.
the answer is yes, the mass of the coin remains reasonably the same while the volume generally decreases. If you set up everything just right you can actually make the coin concave.
You'd have to measure it, but I'd say it's highy unlikely the density increases. Metals already form into very compact atomic lattices and even experiments that aim to emulate pressures and temperatures in the earth's core don't see a change in density. My best guess would be that the sides contract and the middle bulges out maintaining the coin's volume (mostly; you're probably losing a tiny amount of material in the process).
AdenineMonkey It has been tested... it's really counter inuitive but it does work. I should really have qualified that the change is tiny. Project Stomper got a change of a fraction of a percent out of 100kA at 6kV. Apologies for the confusion.
If you reversed the current on the coil the resulting induced currents in the coin would also be reversed, so would still be opposing the current in the coil, so the coin would experience exactly the same forces.
I know that this video is old, but, I was wondering something. Does the position of the coin effect how it shrank, like placing the coin perpendicular to the current? Or, what would happen if you twist the coin into a different shape.
how does shrinking affect the metals properties? how much "harder" is the metal after being shrunk? is it less or more conductive afterwards? How much does it change the melting point? what happens if you do it to solid mercury?
@MadMulberry: Yes, but the question is what the reference of that 10% is. The GBP is not expected to change much, and a significant part of that country's economy is local (in the case of Great Brittain). Therefore understandable they at least consider a brexit. Back to physics girl: in the old days the real value of a coin was directly related to the metal it was made of, and the purity thereof. When you shrink a silver or gold coin it does not really devaluate economically.
True Explanation- The coin is the size it is because of the quantity of energy in each atom. The distance the atoms are apart depends on this energy value. Less than 1% of the metal is "solid" the rest is space. If the energy value is increased ( e.g. by heating it in a flame ) the coin will expand (the atoms have moved further apart) . When the electromagnetic field is applied a massive shock is produced that displaces a portion of the energy within each atom. The reduction in energy causes the distance between each atom to diminish, the coin is smaller. A similar effect occurs if the coin is cooled (taking energy away from the atoms) - it goes smaller.
Ok, but what happens in the coin? On an atomic or molecular level? Does that mean that metal is like a sponge, full of holes, waiting to be filled with the re-arranged atoms?
Back in the mid to late 60's I was doing high voltage experiments. I was building Tesla coils, experimenting with power transmission through the ground, and experimenting with high intensity magnetic fields. Very dangerous experiments!
Does shrinking a quarter alter the magnetic or conductive properties of the quarter? Will it pull current from the domain wall of two magnets if sandwiched between them?
What exactly is lost in coin shrinking? Metals are malleable and ductile. Does density increases? Or some metal is lost? But then how it keeps shape and carvings? Does weight remains the same?
Hello, could you try that same experiment but this time try out my theory, by adding some kind of fluid like petroleum jelly to lightly coat the coin before doing the experiment, it might reduce the deformation (well it's deforming it anyway by shrinking, but you get my point,,,LOL) and it might help reduce the discoloring as well, just a hunch of mine, and I could be wrong though,,,LOL. well thanks, oh and I luv your work, you're an inspiration to all young girls around the world, I know, I have a daughter.!!! :)

With all that amperage and megawattage produced, how much does it cost to shrink a coin? (i.e. electric bill)
Great question! gonna look into that.
I think that the short time used in the process, does not cost so much...
the interesting thing is, not a lot really. you charge the capacitor using low current, high voltage. i dont know how many amps they pull from the wall, but if its a standard 110 outlet, the maximum would be around 15amp, and only for the time needed to charge the capacitor. thats whats great about caps. you can charge them with very low current and high voltage slowly, then in a blink of an eye dump all that energy, creating massive amounts of current output. thats how theyre getting something like 50kamp(?) and millions of watts (for literally fractions of a second) out of a power supply (the wall) that cant push more than 1500w or so.
basically, it probably doesnt cost all that much at all. a few cents maybe.
+m4xwellmurd3r forgot to mention, if they were to push 1000w from the wall through the transformer to charge the capacitor, they would be charging it at a rate of 125mah or so. very low current (since when you step voltage up current drops)

Like Dianna said, the coins are basicly squished from the ouside in and get a lot fatter. From my understanding the volume just gets redistributed.

I'm literally learning about this stuff in magnetism in school right now and I NEVER thought it could be this cool. Looking at how these forces and laws actually work in real life makes me want to go back and learn about them, something that hours and hours of theoretical teaching could never do. Thank you for making this video!!
So it's a 1/8th now.
Hmm, seriously though, is this similar to the effect inside a black hole, which ends up with a super heavy dwarf star at it's center??
I think it's the other way around. A black hole just has a point of insane mass at its center. once, it may have been a super heavy star, before its super nova.
@@phoule76 So it's more like Donald trump then.
Yes. The matter in the center of a black hole gets shrunk when passing through, and this process creates exotic particles and a giant electromagnetic field. The difference is, black holes have enough material so as to not overload their total energy capacity, whereas with this experiment, they oversaturated the copper and coin's ability to stay stable during such a massive voltage drop, causing it to explode. It's the same as trying to force 1000 gallons of water per minute through a tube only capable of 100 gallons per minute; the tube will definitely explode if you try it.
@@wordreet Yes, matter does pass through a black hole. At that point, any solid matter would be shredded into its base waveform/particles, resulting in pure energy, and as we know a moving energy source creates a magnetic field, hence the giant magnetic fields surrounding black holes.
The alternative explanation can be thrown out the window, since they literally claim the laws of physics break down when black holes are concerned.
What would happen to a diamond or a q-carbon crystal under your high magnetic field???
wow i just found your channel and am totally in love ! Subscribed !
I love the topics you choose and most of all - the presentation.
Keep up the amazing work ! :D
"Shrinking currency" or "Shrinking, currents-y"? I'll see myself out.
Quality comment.
Does it stil weigh the same?
yep
@ about 1:40 she shows a side view of some very deformed coins and says something like it only shrinks from the sides but bulges out the middle. I imagine the volume would stay about the same. If not there would either be a mass or density change. Perhaps with all the deformation and heat some of the material sometimes gets blasted off. In that case only would it weigh less.
So it still works in a vending machine?
Nope, pretty sure vending machines need correct diameter coins
if it weighs the same then could people shrink a 20Lb ball into a pea shape ball with enough power? This could be a way to create a black hole.
Is the density of the coin actually increasing, or is it just making the coin thicker?
I think she said it gets thicker but which could mean that the density and therefore the volume stay the same.
i wonder if the current frys the 'space' between molecules ?
@@mattsowerbutts4163 There are no molecules in coins. Only metal atoms with a network metallic bonds between them. I don’t know if the electricity can change the length of those bonds, but there are no separate molecules to squeeze together.
@@marcochimio hmmmm, what about sub-atomic space?
@marcochimio - Why not just watch the video and find out?
You can wrap the outside of that coil with a magnetic sleeve, and effectively 'push' the outer bands of EM force inward, doubling the power in that work area. Just so ya know.
honey i shrunk the quarter
Great video and topic, thank you. Perhaps I missed it but shouldn’t it be explained that the rapid power input to the coin presumably also heats it towards its melting temperature which facilitates its deformation in compliance with the electromagnetic forces…?
3:18 that outlet looks like it knows what's coming...
Who has 10w light bulbs? Do you live in 1950? We have LED now. SO I assume most people.
Your excitement is contagious. Great videos! Keep up the good work!
Our currency has been shrinking for over a 100 years
Would it be possible to shrink it so many times, it becomes so dense, then collapses on itself to create a black hole...
I thought I heard somewhere that if there were to be a tiny black hole it would be extremely powerful until it eventuallly grew and consumes the earth and all that surrounded it
The serious academic physicists that I've heard have indicated otherwise. For example, when there was some pop-hysteria about the possibility of the LHC creating a black hole with its high-energy collisions (up to 13 teravolts!), the physicists did the calculations and pointed out: "Um, even if it did, they would be so tiny that they would evaporate before they could affect anything else."
A black hole a kilometer across would definitely rip the earth up. However, it would have a mass something like 10% of the entire sun (which is a million miles across), and it would probably last longer than the current age of the universe. However, a black hole the mass of a single coin would come and go in a flash before it could do anything meaningful. It's an exponential scale both ways: big = lasts super long, but small = disappears super fast.
You can apply the "Nature abhors a vacuum" principle. A big vacuum (a big black hole) sucks up a lot of nature faster than it can be evaporated, so it maintains itself; but a small black hole gets sucked out of existence by nature almost immediately.
animist channel, plus it would explode and destroy the earth with a force of 5000000 megatons of TNT?
Sorry for bringing up a dead thread, but if you watched Kurzegaht's video on coin-sized black holes, then you would know that the coin black hole will explode with a higher power than Hiroshima, so maybe it won't be harmless.
Thanks for joining in -- new thoughts are always welcome :) You bring up a fair idea, but in the case we were discussing, it was not a black hole the SIZE of a coin, but a black hole with the MASS of a coin (a couple grams). There is a vast, vast difference between the two. A black hole the SIZE of a coin would have the mass of a mountain range, and yes that would be bad if it formed on earth!
Likewise, if the LHC had managed to cause microscopic black holes with their particle collisions, those would have had the mass of a few protons and evaporated away instantly, with no effective gravity to pull in anything from the surrounding area. At that scale, gravity is so weak as to be meaningless compared to chemical bonds and other factors, and so a mosquito with billions of particles in it can just hang on the ceiling because of a little surface tension.
When we start looking at things like black holes, the exponential differences in size, mass, gravity, and time get so extreme that it is easy to be misled by our everyday intuitions. We get into the realm of comparing infinities and inverse-infinities, and our brains are not naturally wired to do that. Intuitively, we are used to comparing feathers to rocks, maybe, but the relative differences in these cosmic events are many orders of magnitude more different from each other.
I hope that helps...
Very cool. But, what happens to the structure of the coin? The mass must remain the same because you're not removing any from the shrunken coin. Is it imploding under the forces? Much the same as imploding the nuclear material of a fission bomb to create critical mass? So, the coin will weigh the same in both forms, but the internal structure will become more dense?
The guy would be SHOCKED by his current bill XD
Not really, 1 MW for 0.001 s = 1000 W for 1 s = 1 W for 1000s. Charge slow, discharge fast.

Title: How to shrink a quarter using electricity
Did I see a comment along the lines of a "waste of electricity"? Well, let's see: At a rate of $0.1 pew kW-hr, that's 26,496,000W x 30uS, or 26496kW x $8.3ee -9 = 0.002 cents- two milli-cents per shrink or 500 coin shrinks for a penny. Plus It's legal as long as you you don't sell the quarter for more than 25 cents, just add a working (?) fee. I have been into this for a while, and am working on a "re-usable coil" with a very uniform shrink (% per kl). And, yes, the mass remains constant.
atta-Girl!
--dalE
I thought you must have made a mistake, but no, I guess it's hard to judge how long a microsecond really is, because it really adds up to 2,2 millicents for 0,22 watthours... Amazing.
Maybe I missed it, but what is happening to the quarter at a molecular or atomic level that causes it to shrink?
Yea the main question as stated below is "Will this cause the mass of the coin to become more dense" If it does the applications would be extraordinary.
Yeah! Ant-Man suits for everyone!
the answer is yes, the mass of the coin remains reasonably the same while the volume generally decreases. If you set up everything just right you can actually make the coin concave.
You'd have to measure it, but I'd say it's highy unlikely the density increases. Metals already form into very compact atomic lattices and even experiments that aim to emulate pressures and temperatures in the earth's core don't see a change in density. My best guess would be that the sides contract and the middle bulges out maintaining the coin's volume (mostly; you're probably losing a tiny amount of material in the process).
AdenineMonkey It has been tested... it's really counter inuitive but it does work. I should really have qualified that the change is tiny. Project Stomper got a change of a fraction of a percent out of 100kA at 6kV. Apologies for the confusion.
KaitharVideo I can't find anything on density change from a quick google search on project Stomper. Do you have a source for that claim?
Defacing Currency get the jail cell ready. Still fascinating, pretty cool!
can you still shrink a shrunken coin?
can you "unshrink" a coin?
If you reversed the current on the coil the resulting induced currents in the coin would also be reversed, so would still be opposing the current in the coil, so the coin would experience exactly the same forces.
does it change the molecular density of the coin? how does it affect the distance be3tween the molecules and the distance between the atoms?
Are y’all ready for this?...
*Space Jam starts playing*
neat... now - what would happen if a living thing was put in there rather then a coin?
it would not survive.
time travel
It would basically experience a highly focused lightning strike, and probably explode.
+Physics Girl There is no kind of extremeophile capable huh?
ant man
I know that this video is old, but, I was wondering something. Does the position of the coin effect how it shrank, like placing the coin perpendicular to the current? Or, what would happen if you twist the coin into a different shape.
Wow, Really cool! Subbed
So.. the coin is now smaller than it was... is it thicker than it was or did it's density change?
i assume the weight of the coin is still the same.
how does shrinking affect the metals properties? how much "harder" is the metal after being shrunk? is it less or more conductive afterwards? How much does it change the melting point? what happens if you do it to solid mercury?
"How to shrink a quarter with a high voltage electromagnet"
Disclaimer: This is not a "how to"
Good for you. Showing a bunch of criminals who are defacing currency.
If it gets thicker, and the volume remains constant, it's not actually shrinking.
So, what if you add cryogenic fluid or liquid nitrogen to the coil?
Another good way to shrink currency, by about 10%, is for a E U country to vote to leave the European Union. :-)
@MadMulberry: Yes, but the question is what the reference of that 10% is. The GBP is not expected to change much, and a significant part of that country's economy is local (in the case of Great Brittain). Therefore understandable they at least consider a brexit.
Back to physics girl: in the old days the real value of a coin was directly related to the metal it was made of, and the purity thereof. When you shrink a silver or gold coin it does not really devaluate economically.
True Explanation- The coin is the size it is because of the quantity of energy in each atom. The distance the atoms are apart depends on this energy value. Less than 1% of the metal is "solid" the rest is space. If the energy value is increased ( e.g. by heating it in a flame ) the coin will expand (the atoms have moved further apart) . When the electromagnetic field is applied a massive shock is produced that displaces a portion of the energy within each atom. The reduction in energy causes the distance between each atom to diminish, the coin is smaller. A similar effect occurs if the coin is cooled (taking energy away from the atoms) - it goes smaller.
Sounds good to me!
I gave you a 👍!
what about the weight of the coin is it the same after the process ??
Obviously. Why would the weight change when the mass stays the same?
Abdalla Jaber what changes is the density
Ok, but what happens in the coin? On an atomic or molecular level? Does that mean that metal is like a sponge, full of holes, waiting to be filled with the re-arranged atoms?
It just gets thicker.
Try it with a Plutonium coin?
Oooh, I want some shrunken quarter earrings.
Wastage of electricity
So the volume of the coin is decreased, but the mass remains the same? Does this strengthen the coin?
So now we know how Rick Moranis did it in "Honey I Shrunk the Kids"
so how Much Amplitude of Em Wave are Generated During Discharge , i mean , is it able to kill your cellphone if you are Standing there ??!!
Disclaimer ,” this is not a how to do”. Title says how to shrink a quarter
Uffff
5:55 Imagin that! you only need 88mph and 1.5 Gigo' watts to go back to te future!
Isn't it illegal to deface\damage U.S. currency?
no. only if you plan to sell it.
Back in the mid to late 60's I was doing high voltage experiments. I was building Tesla coils, experimenting with power transmission through the ground, and experimenting with high intensity magnetic fields. Very dangerous experiments!
IF ONLY I COULD READ THE LABEL AT ABOUT TIMESTAMP 2:22 !!!!
Does shrinking a quarter alter the magnetic or conductive properties of the quarter? Will it pull current from the domain wall of two magnets if sandwiched between them?
""A pinch is the compression of an electrically conducting filament by magnetic forces"
What exactly is lost in coin shrinking?
Metals are malleable and ductile.
Does density increases? Or some metal is lost? But then how it keeps shape and carvings? Does weight remains the same?
It gets thicker proportional to the reduction in diameter
Can you keep shrinking the coin?
Pffft. That ain't nothing. Doc Brown harnessed 1.21 Gigawatts.
Great Scott! 1.21 GIGAWATTS?!
Yup. 1.21 gigawatts.
Hello, could you try that same experiment but this time try out my theory, by adding some kind of fluid like petroleum jelly to lightly coat the coin before doing the experiment, it might reduce the deformation (well it's deforming it anyway by shrinking, but you get my point,,,LOL) and it might help reduce the discoloring as well, just a hunch of mine, and I could be wrong though,,,LOL. well thanks, oh and I luv your work, you're an inspiration to all young girls around the world, I know, I have a daughter.!!! :)
I know no how my stockbroker shrank my investment, put in,£20,000 drawn out £18,000.
are these machines made, buy the STOCK MARKET????????????
