You don't know how to use thumb, curling fingers and direction of force. You made everythibg confused even if it is rule taught in schools. Nonsence. Get an actor who knows the basic science 😂😂😂😂😂😂😂😂😂😂 stupid this person is.😂😂😂😂😂😂 corupted minds of students with wrong demo.😮😮😮😮
Anybody hear about tesla working on a way to make capacitors more efficient to reaplace batteries on all of future electronics and power requirement issues like this
If you set the length in F=ilB to the length of the rail gun then you will get the force on the rails which pushes them outwards, not the force on the projectile. The length should be set to be the portion of the projectile length, the distance between the rails, to get the force on the projectile. Just for anyone wanting to build one :)
Why couldn't make the sabo out of a superconducting metal and cool the whole apparatus using liquid hydrogen or helium causing the round to magnetically levitate, thus both reducing friction and keeping the railgun from overheating. To me this seems like a no brainer cause metal is more conductive at lower temperatures anyways. If I was designing one this is how I would do it. I would also not make the rails in 2 straight lines, instead I would spiral them keeping the distance between them equal to the end of the barrel. Spiraling them would allow you to shorten the barrel and at the same time it would impart spin to the round making it fly straighter and longer. For all I know this is how the military already does it.
Something clearly doesn't add up. The so called Lorentz force can not be in the direction of current, be it positive or negative. Now having that in mind which direction should the projectile travel. I can not be parallel to the them rails. I think you have a hick up there... 🙂 Think about this: Place your right hand in front of you. Palm facing up towards the ceiling, ( call it positive Z axis) this is the direction of wait for iiiit, not magnetic field, your palm shows North of the magnet facing up. That is much more clear. This means there is magnet underndeath your hand with it North pole facing up. Now your fingers are straight ahead of you pointing away from you, (call this positive Y axis) This shows the direction of current in whatever conductor. Now your thumb, yes your right hand thumb pointing to the right ( call this positive X axis), is the force on what? The force on the wire. Did you catch this, the force is on the wire that is carrying the current. This mean what? The projectile must be the wire that is carrying current and the force ( the magnetic North pole that must be orthogonal in Z direction) if the projectile is to move to the right and the current must move straight ahead from you towards the page on that wire. Therefore the magnetic North pole must face up from the bottom and you better get the south of the magnet up above for more intensity. Do you understand? And you must have positive rail at your hand and negative away from you on the projectile itself as a conductor. Now those rails are nothing but keeping the projectile in line. These dryings are way deceptive and general. it means nothing. Also there is tremendous repulsive force between the two rails, if they are carrying lots of current for instance. So they better be mounted secure.
If they are high-school then they are very well articulated and they even know something useful. If they were engineers - I'd say they could do better in politics :o)
I think you should add a cooling system like the ones nuclear subs use, as for the wrapping try using structural designs and different Alloyed combinations, power source we have yet to really use the ocean Currents for the Generator, that would produce more then enough energy. Just my thoughts
1:26 Actually, the electric current does not go through the positive terminal first, it is the opposite. Dc current flows from Negative to Positive. (we had originally thought or assumed it flowed pos to neg). 'Convention' does not change fact, we found that the earth is not flat, so we stopped making maps and navigation tools for a flat earth. 'Electron Flow is an inconvenient truth' I'm not advocating book burning. But there should come a time where we start using electron flow instead of 'conventional' theory.
Yes but convention say's positive to negative. If you use electron flow, then flemmings handed rules don't work, and semiconductor nomenclature becomes illogical.
You left a crucial thing out and everyone misses it. Show also the direction of magnetic field on the projectile as the current flows through it and see what you get.
Your theory is completely wrong. 3:58 The magnetic field is circular and the force is always perpendicular to the field. You need an actual object on which the force would be exerted. 4:20 Two conductive lines with current flowing in opposite direction push away from one another - the force is repulsive, not attractive. 4:56 the mechanical sandwiching or "squeezing the projectile out" is also wrong. For the same reason as last point. Railgun would work even if the projectile was just a conducting stick placed on top of the two power lines with no mechanical forces working on them. If the squeezing theory was correct the projectile would just be welded onto the rails. The drawing on the left actually gives the correct picture. The real reason why the railgun works is that the two lines produce a magnetic field in the same direction in relation to the current flowing through the projectile (into the whiteboard) which is why the resulting force is perpendicular and sends the projectile along the rails. I don't know what level you are but I hope this isn't a university.
😈 you are wrong little monster. The fastest a man ever went was when I seen my ex wife who is a runway model out at the airport coming to try and get us back together. 😳
There is no need in mentioning "positive" or "negative" poles. In general huge capacitors are used as the power sources, and during their discharge(i.e. the projectile acceleration process) electromagnetic oscillations occur, and "the poles" periodically change, and it does not change the Amper's force diraction(it is obvious for someone who knows electromagnetism on a school level), and yes, Amper's force when we are talking about solid projectiles being accelerated. Lorenz force is the force which acts on the charged particles(in ionised gas for example) in magnetic filed.
Thanks for the video, wasn't perfect, but a great job non-the-less. I was actually thinking about alternative ways for rockets to get into space aside from burning tons of fuel. It was a terrific presentation and I urge you on making many more. 👍
I am kind of concerned about g-forces being shot out a rail gun. 8,000 feet per millisecond would turn biological material to mush unless you had a inertia dampening system.
Hei guys. Awesome video. But I believe you guys made a huge mistake. I have one correction to make. L is not the length of the rails.. It is the length of the projecttile. The lenght of the rails has no influence to the force/speed pushing forward. The rails actually try to ecape each other that is why they need to be very secured to a base so they cant bent or push away from each other. Froce is only made from that little piece (L). So with the hooked up current the force is actually going the other way then you guys drawed down.
Just a minor nitpick :) the "length" of the projectile is actually it's width ie the separation of the rails. You probably knew that, but I thought it would be nice to clarify :)
Have you ever thought about using super conducting magnets which utilize a super cooling method to counter the heating issue as well as possibly add extra force to the projectile?
an area of study that I'm looking into is customizing the permeability and permittivity of the projectile material to greatly increase the speed of the projectile.
Well, unfortunately, this is not how the right-hand rule works, or how a rail gun fires. I can rotate my hand in any direction, keeping my thumb in the direction of current and my fingers properly oriented around the wire in the direction of the magnetic field. Therefore, the force can be in any direction. You all have good pictures though.
Thank you for the excellent primer on railguns. Great introduction to the concept. One point I would correct. The force that moves the projectile forward is the current crossing the sabo. Thumb pointing toward negative rail, fingers curled toward back end of / start of rails, force pushing back, forces projectile forward.
Also the forces on the rails push the rails apart, not together. Still, apart from the physics errors at 2:52 and 4:43, a well presented and watchable video.
2nd explanation is better but little bit wrong i think “the right hand law” explanation he had to say that the induced force are made only when magnetic field hit the current wire not just made automatically
(F=iLB) is BS do your own math. how much B would be generated from your currency? it will be way more efficient to use permanent magnets for generating the magnetic field. also L isn't the length of the rails. it is the width between the rails.
12 seconds in and you're already wrong. The first darn thing you say. People regularly travel faster than the X-15 (about 5 times faster) when they take rockets into orbit. They're ultimately going about Mach 33 when they reach orbit.

Thanks! We actually built something like that in our physics class recently, though not as powerful, for, I believe, obvious reasons 😂
Thx bhai
This video is just a cartoon. No physics.
I already see a redneck doing the closest functional thing

Ok so how do we get by the radiation belt surround the earth,and why have we not been to the moon since the first time?

This is the same principle that UFO's use for propulsion.

Another kilometer / metric Globalist. :facepalm:
Well done.
Excellent, just so good, on point, clear and detailed at the same time. Thanks!
ok so for us dumb people... this works basically like a more complicated fly wheel blaster
Wait what about the simplest magnetic train? The armature doesn't have its own magnetical fields but still work...I'm so confused...
These forces were noticed by physicist Fred Railgun. Hence the name

Later he divides $25,000 into $1.5 million and gets six. Not that this couldn't happen in actual practice. 😞
Hello .Why does my projectile boil between the rails

It might have to be a low accelerating rocket, but nonetheless it’d be awesome.

Oxygen can be fed in as they did on the shuttle.
