Great idea! I giggled when you struggled with the tools near the magnet. I know exactly how challenging that can be... You know its coming and prepare for it, but you just can't compensate for the quickly increasing strength of the magnetic field near the magnet x)
I did some work on some magnetic stuff back in the day, we had some special alloy tools which made it a lot easier. I think they were just stainless steel, but I can't remember, I remember them being expensive however.

You should use flat steel similar to pallet strap. I've seen it used in some power transformers. This will eliminate most of the air gaps created by the round wire. It should give you a higher density.
@@TechIngredients Could you use shorter strips of metal and layer them similar to bricks first then wrap the wire over the top so as to bring the field lines closer to the gap? Or have I got the wrong end of the stick?
Wouldn't recommend it. People build those things because it's easy and the tools are free, but if anything breaks, tech support is a nightmare. You might think you'll just fix it yourself with some spare parts from Granddad, but big surgery made that illegal.

This was simply a joy to watch. When you were saying that having to work with big magnets could be “sketchy” I thought, that’s a phrase I’ve never heard here before. It must be true. It was great to just see the laughs with the tools and general mirth in the video. Great as always.
The father of the main presenters son would be a heck of a teacher in school. So clear spoken and easy to understand. How about ferromagnetic fluid? You could make a plastic or aluminium sealable casing and pour the fluid in the casing
I used to work at a transformer company and they used sheets of high-silicon steel which were layered together to make a laminated core. Apparently it allows a higher magnetic flux density than solid steel. However I can see that working with sheet steel edge-on to a powerful permanent magnet is a recipe for truncated fingers, so your wound coil idea is interesting.

I'd like to thank you and the people involved in your UA-cam videos. I work the Natural Resouces Canada in a combustion lab and we are in the process of designing and building a Magnetohydrodynamics project. This subject is not aligned perfectly with our expertise. We have learned alot from your videos and it has contributed greatly to the final design and hopefully the success of the research.
Amazing that you can make a relatively uniform magnetic field with almost a whole 1 Tesla of field strength. The strongest magnets I ever used were 3 Tesla, and those were liquid-helium cooled superconducting magnets in a Bruker Spectrospin 300 MHz NMR machine about 15 years ago. Go back about 40 or 50 years, and 1 Tesla would probably have been enough to do some basic low-field NMR experiments. If those super-strength rare-earth magnets had existed then, I'm sure they would have been used for that! Of course the added problem with NMR is that the field strength around the RF probe (which is where the sample-tube goes as well) has to be ABSOLUTELY UNIFORM - no variation at all. NMR instruments typically do this with secondary electromagnet coils called shim-coils, in which the current is adjusted to even out the field strength. In the early days this was done manually while keeping your eye on the field-sensors, but this utter tedium was eventually taken over by a computer, which could do the adjustments much faster. I wonder if there would be a way of combining the permanent magnet array you show here with a bank of electromagnetic shim coils to make a perfectly uniform field? A standard NMR sample tube is only 5 millimetres wide (with a 40 millimetre sample depth), so the cross sectional area over which the field needs to be uniform is fairly small. If you could do this, you would be on your way to making the core of a home-made NMR instrument. Minus all the RF transmitters, receivers and amplifiers of course, which are a whole other headache.....
Very ingenious solution! I worked on MRI's a short while and the experience you had with the channel locks was a real problem I had. Most of our tools were beryllium alloy so non-ferrous but drilling access holes for fiber optic cables around a +2T magnetic was an experience I never wish to repeat. Wonderful video keep them coming!

I wrap lots of wire and built an aluminum jig/fixture that goes on the lathe and uses the threading settings. Hardest part is like you mentioned chip cleaning before when using magnets. I spend more time in prep cleaning before than I do wrapping.
I didn't even think of how the field would interact with the tools, I was wondering what was happening. Interesting concept, manipulating a magnetic field is significantly more involved than I thought!

@@robbiejames1540 if you change the current in a coil, it creates a changing magnetic field. That changing magnetic fiend induces a current in a conductive metal neat by. The currents in the metal create their own magnetic field in opposition to the initial magnetic field that induced the current. The result is a repulsive force pushing the conductor away. A Pulsed induction thruster uses a coil to ionizes a gas for a working fluid to use for a thruster to genetate an intense and rapidly changing magnetic field. once the gas is a plasma the changing magnetic field from the coil induces a current in the plasma and that current in the plasma makes its own magnetic field opposing the magnetic field in the coil thus pushing plasma away at a high speed for thrust. en.m.wikipedia.org/wiki/Pulsed_inductive_thruster

Not only are your videos inspiring technology/science wise, they also make me aspire towards having a tidy lab and to develop a more pragmatic approach to my builds and projects. Looking forward to next video whatever it may be!
Excellent video as always! Please don't stress yourself on the whole metric vs imperial measurements just to please some commenters here, the people who it really matters to can easily convert. You make astounding content and we all look forward to you sharing your ideas!
Actually, I don't. It's a bit of an inside joke. The most avid proponents of metric acendency tend to be the same people that look down on Americans because most of us are not multilingual!
Whats really funny is that the Intelligentsia who call us stupid for not using metric as the superior way, never get the joke in the joke when we tell them to come back when they make it too the moon. Not only haven't they made it to the moon unlike us Imperial users, they haven't made it even though using the superior metric systems... :)
Speaking of myself only; I am not sure how useful this is for me but I guarantee you it is mesmerizelingly interesting. I haven't been exposed to a more interesting site than yours and you have a gift for explaining the principle properties of these subjects in such a through and clear way that I "almost understand" them! But, as I'm sure that the majority of the viewers would agree, we aren't in your league. Please continue this facinating site, I haven't found any other sites that come close in interest level and especially not in your scientific method and working knowledge. I'm a big fan!
Copper is not ferromagnetic and neither is aluminum. Although this wrapped magnet looks something like a transformer, the wire serves a completely different function. The wire in a transformer guides the electron flow and it is these electrons that generate the magnetic field. This steel wire guides the magnetic field which is generated by the permanent magnets in the center.
When you don't want the nut to move, use two and tighten them toward each other and that could alleviate pressure on the carriage device in the middle. You could have saved on the bearings at the ends. Cool video!
One of the best channels on UA-cam. Was wondering your background. Any videos talking about you, or telling what you did before or currently? I guess College professor.
The same people who make sure it gets fed to you make sure you have no idea of what the magnetic field actually looks like, if that helps you gather to whom they are affiliated with. This is a common thread with many of the YT technology channels today. They like to high five one another in the comment sections as well. Probably right next to each other having a coffee thinking about how to gloss over any comprehension of simplicity in design and why that is.
@@cannaroe1213 LOL I like it. The grants and funding suppliers at work to keep the same page from ever being turned. Simple comprehension of magnetic fields shows that we've been handed a misrepresentation in crafty sleight of hand.
Good Idea, even though he did say its only the cross section that is significant. But there would probably be some increase. That's basically a packing problem. Like you said it probably wouldn't be worth the cost for the few percent(if that) increase unless you had some laying around. Or perhaps even just cut long strips of sheet metal.
My intuition (which is likely to be completely wrong) makes me think that two opposing C-shapes out of steel ribbon would be even better as guides but it would not be as practical to build, especially not in a continuous additive process.
Clem Taylor agree! cold rolled steel wrapping around as used in low frequency transformer style would increase permeability which could increase the inner flux( my thought). Improve rejection to the eddy current to? if the experiment required to reduce the hysteresis loop of the wrapping material then could be a good idea. Good comment Clem. Keep going! Very informative and recreative topics
I mean this in the best possible way, this gentleman reminds me of a cross between Mr. Wizard and Mr. Rodgers. You older folks like me will remember both.
You were talking about *_magnetic flux density_* (in tesla), not the *_magnetic field strength._* Please try to use the correct term. I know everyone uses the terms incorrectly, often including myself, but it´s a big difference.
Ha! reminds me of the time I needed a pole for my rain gauge. So, idiot me sawed the head off my mum's broom and broke the blade of my dad's hacksaw in the process. The light of truth hit me when the broom head hit the ground: Annoying one parent was dumb, both together and I was dead. My dad's comment: 'I told you to never use a metal cutting blade on wood.' He attaches the broomhead back to the handle and takes me to buy a new one for my rain gauge.
Sparrow's claw? Is that a Vesper Sparrow, Savannah Sparrow or a Grasshopper Sparrow? :) I hear somewhere that Crowsfeet were used as a measure of time in some places.
Thank you for sharing. Very informative with a touch of mild humour (I'm Canadian). I have have a thought for your consideration if you are planning to wrap more magnets. Swap out the threaded rod for a wooden dowel slightly longer than the mounting bracket. Use non-ferrous materials to secure the magnet assembly. Attach a drill to one end of the dowel to drive the winding (a lot less strain on the arms, hands and fingers). Would also suggest that you fabricate a spool to hold the wire and run the wire through a series of dancer rollers or pullies. This will help to apply a more consistent tension on the winding, not to mention that this would free up your videographer to do videography. Just saw the upload date. Story of my life, the ideas and witticism come well after their usefulness, oh well. Carry on you're doing a fine job.
I, as one, feel that having intelligent people presenting the content works much better, but having worthwhile content on the show makes everything interesting to watch also I had to laugh a bit when the proper tools were not right there ready to use. Another good show, thank you. Michael said that bye for now my friend.
Awesome video! Discovered your channel a few minutes ago with the air conditioning setup. Thanks for that. The liquid dessicant stage gave me a good idea for a project where I need to control humidity. Awesome channel!
Excellent Video! Liked ! With that many wraps I would have brought the threaded rod out one end of your frame and used a cordless drill to slowly turn the assembly and that would have help you wrap that much more quickly!
Channel deserves much more subscribers compared to most others that use gimmicky graphics, and borrowed filler content 👍👍. Wondering, what would happen, if the wound bobbin(made of laminated mica) of steel is taken out and melted to form a solid block(easier said than done). On another note, seems like an efficient way to laminate(assuming a thin high temp insulating varnish on the steel wire), to make a low frequency(several hundred Hz)power transformer core, without needing ferrites and high frequencies, while still almost eliminating eddy currents without using the typical laminated El steel plates. Just some 💭
Very clearly explained and demonstrated. Thank-you. At those field densities, you're within an order of magnitude of the field strengths of superconductor electromagnets - and for a much smaller cost, in a safe manner, albeit within a much smaller volume of influence. You've gained a subscriber today.
Thanks! If you can afford to reduce the volume further, two tapered, steel pole pieces in the shape of a pyramid or a cone can more than double this field strength.
@@TechIngredients Yes, it's an old idea which has been used professionally. I have a magnet which was rescued from a scrapped 1950's magnetron and which uses that technique to concentrate the field.

Great Idea! Helped me a lot. Thank you.
Seeing the title I was hoping we would finally get to see some cerrolow 136 being shot into orbit by that monster magnet yoke... but winding magnetic circuits is also an interesting idea :).
This guy is awesome, its like a fun lecture every video....wait.......it is. very easy to follow, great stuff.
Not only are your videos inspiring technology/science wise, they also make me aspire towards having a tidy lab and to develop a more pragmatic approach to my builds and projects. Looking forward to next video whatever it may be!
Definitely one of the top channels on UA-cam. 👍
Thanks!
Man, you are a mine of knowledge !
I like the way that you explain the process
Interesting. Makes me think of Edward Leadskalnin works and why he used so much iron with his builds.
I always enjoy your videos. Thanks for being a great teacher.
Excellent video as always! Please don't stress yourself on the whole metric vs imperial measurements just to please some commenters here, the people who it really matters to can easily convert. You make astounding content and we all look forward to you sharing your ideas!
Actually, I don't. It's a bit of an inside joke. The most avid proponents of metric acendency tend to be the same people that look down on Americans because most of us are not multilingual!
Whats really funny is that the Intelligentsia who call us stupid for not using metric as the superior way, never get the joke in the joke when we tell them to come back when they make it too the moon. Not only haven't they made it to the moon unlike us Imperial users, they haven't made it even though using the superior metric systems... :)
Useful to me in many ways. Thank You.
Very cool but i was chomping at the bit to see the rest of the water cooled solid state refrigeration system
Speaking of myself only; I am not sure how useful this is for me but I guarantee you it is mesmerizelingly interesting. I haven't been exposed to a more interesting site than yours and you have a gift for explaining the principle properties of these subjects in such a through and clear way that I "almost understand" them! But, as I'm sure that the majority of the viewers would agree, we aren't in your league. Please continue this facinating site, I haven't found any other sites that come close in interest level and especially not in your scientific method and working knowledge. I'm a big fan!
Thank you!
Bailing wire! Almost as useful as duct tape! Fascinating project.
Baling wire has kept a hundred years, and billions of miles, of Ford products running. And I'm betting there's a stash of it on the ISS.
Man I love this video, and the savvy behind it. Good show!
Would two opposing Halbach array's of magnets also help increase the magnetic field strength inside the gap?
Excellent work! I will continue to watch all
Thanks!
Brainiac & Tech Ingredients uploading _magnet_ videos within seconds of each other :)
I love when Tech Ingredients upload videos. When it´s about magnets I'm in paradise xD
Magnets rock! :)
Your work place is beautiful. Very nice and clean
Thanks!
Would wrapping the copper wire more uniformly with tension help align the magnetic field's better for a higher Tesla Rating???
Copper is not ferromagnetic and neither is aluminum. Although this wrapped magnet looks something like a transformer, the wire serves a completely different function. The wire in a transformer guides the electron flow and it is these electrons that generate the magnetic field. This steel wire guides the magnetic field which is generated by the permanent magnets in the center.
The fast forward is a great way to show things. TOT does that on his machining videos. I'm seeing the makings of a rail gun
This is a modern, much cooler, Mr. Wizard show!
When you don't want the nut to move, use two and tighten them toward each other and that could alleviate pressure on the carriage device in the middle. You could have saved on the bearings at the ends.
Cool video!
One of the best channels on UA-cam. Was wondering your background. Any videos talking about you, or telling what you did before or currently? I guess College professor.
Ryan Fiorini They're notoriously secretive about their identities.
@@brainmind4070 Thanks for that. I just started watching.
The same people who make sure it gets fed to you make sure you have no idea of what the magnetic field actually looks like, if that helps you gather to whom they are affiliated with. This is a common thread with many of the YT technology channels today. They like to high five one another in the comment sections as well. Probably right next to each other having a coffee thinking about how to gloss over any comprehension of simplicity in design and why that is.
@@lifeunderthemic .The Ellumin-Magneto-ati
@@cannaroe1213 LOL I like it. The grants and funding suppliers at work to keep the same page from ever being turned. Simple comprehension of magnetic fields shows that we've been handed a misrepresentation in crafty sleight of hand.
Wish I had time to just set and watch all your videos, great stuff!!!!!
How do you make a stronger magnet?
Get it to pump some iron and wrap the flux out of it.
Nice!!! two water-bending magnets placed close together!!!
How about using steel ribbon instead of wire? I'd imagine it would be more expensive, but it could be easier to wrap and far more uniform.
Good Idea, even though he did say its only the cross section that is significant. But there would probably be some increase. That's basically a packing problem. Like you said it probably wouldn't be worth the cost for the few percent(if that) increase unless you had some laying around. Or perhaps even just cut long strips of sheet metal.
My intuition (which is likely to be completely wrong) makes me think that two opposing C-shapes out of steel ribbon would be even better as guides but it would not be as practical to build, especially not in a continuous additive process.
The ribbon would work, the result would be more compact, the ultimate performance would be the same and the cost would have been higher
Clem Taylor agree! cold rolled steel wrapping around as used in low frequency transformer style would increase permeability which could increase the inner flux( my thought). Improve rejection to the eddy current to? if the experiment required to reduce the hysteresis loop of the wrapping material then could be a good idea. Good comment Clem.
Keep going! Very informative and recreative topics
Thank you for an excellent presentation of the subject.
You're welcome!
Your an inspiration to us all . God bless you Sir. You too have a lovely evening
Hello, Thank you Kind Sir for sharing your lifes knowledge with me. You Sir are a God send, Thank you for Helping me understand.
I mean this in the best possible way, this gentleman reminds me of a cross between Mr. Wizard and Mr. Rodgers. You older folks like me will remember both.
Very elegant solution!
Thanks!
Magnets how do they work?
Minutephysics did a pretty good job of trying to explain it in a concise way in this video. ua-cam.com/video/hFAOXdXZ5TM/v-deo.html
Definitely magic. Check this out (there are better videos showing the effect but this one is good nonetheless) ua-cam.com/video/r9Kg69cQteg/v-deo.html
it's a fundamental force. it just works. like gravity
@Drinkin' I guess they don't recognize miracles.
As always great professional video.
You were talking about *_magnetic flux density_* (in tesla), not the *_magnetic field strength._*
Please try to use the correct term. I know everyone uses the terms incorrectly, often including myself, but it´s a big difference.
@@invendelirium Yes they are proportional in this case.
It´s just something that can be confusing, making it important to use the correct term.
That would be GREAT for storage rings. So brilliant!
My dad would have smacked me upside the head for trying to use channellocks instead of wrenches to tighten the nuts.
My dad might have had the same thought, but avoided it, fearing an endless debate about why do we have channel locks anyway.
Ha! reminds me of the time I needed a pole for my rain gauge. So, idiot me sawed the head off my mum's broom and broke the blade of my dad's hacksaw in the process. The light of truth hit me when the broom head hit the ground: Annoying one parent was dumb, both together and I was dead.
My dad's comment: 'I told you to never use a metal cutting blade on wood.' He attaches the broomhead back to the handle and takes me to buy a new one for my rain gauge.
Thanks for this video.
Think I am going to call you the "Walking Technical Wikipedia" from now on :)
I want to thank you for doing really interesting things on UA-cam instead of nonsense stuff which their is to much of. Good day and peace too.
Thanks!
@@TechIngredients Sorry for the slow response TI. This method I have used numerous times and I have you to thank. Good day and peace to you too. vf
Lol, I love how annoyed he gets at reciting the values in SI! Because you know, 3 furlongs and a sparrow's claw is superior to SI units XD
Sparrow's claw? Is that a Vesper Sparrow, Savannah Sparrow or a Grasshopper Sparrow? :) I hear somewhere that Crowsfeet were used as a measure of time in some places.
Thank you for sharing. Very informative with a touch of mild humour (I'm Canadian).
I have have a thought for your consideration if you are planning to wrap more magnets. Swap out the threaded rod for a wooden dowel slightly longer than the mounting bracket. Use non-ferrous materials to secure the magnet assembly. Attach a drill to one end of the dowel to drive the winding (a lot less strain on the arms, hands and fingers). Would also suggest that you fabricate a spool to hold the wire and run the wire through a series of dancer rollers or pullies. This will help to apply a more consistent tension on the winding, not to mention that this would free up your videographer to do videography.
Just saw the upload date. Story of my life, the ideas and witticism come well after their usefulness, oh well. Carry on you're doing a fine job.
I, as one, feel that having intelligent people presenting the content works much better, but having worthwhile content on the show makes everything interesting to watch also
I had to laugh a bit when the proper tools were not right there ready to use. Another good show, thank you. Michael said that bye for now my friend.
Awesome video! Discovered your channel a few minutes ago with the air conditioning setup. Thanks for that. The liquid dessicant stage gave me a good idea for a project where I need to control humidity. Awesome channel!
Thanks!
9:30 is the dust beneath the magnet assembly from the threading stripping off or just from the steel wiring?
It's scale from the wire.
i have building a coil based linear accelerator on my todo list and i think this could help in increasing field strenght in that case as well.
Excellent Video! Liked ! With that many wraps I would have brought the threaded rod out one end of your frame and used a cordless drill to slowly turn the assembly and that would have help you wrap that much more quickly!
Great Video I love watching intelligent helpful videos .
Your content is fantastic!
Thanks!
You made my evening scienterrific, thanks.
Channel deserves much more subscribers compared to most others that use gimmicky graphics, and borrowed filler content 👍👍. Wondering, what would happen, if the wound bobbin(made of laminated mica) of steel is taken out and melted to form a solid block(easier said than done).
On another note, seems like an efficient way to laminate(assuming a thin high temp insulating varnish on the steel wire), to make a low frequency(several hundred Hz)power transformer core, without needing ferrites and high frequencies, while still almost eliminating eddy currents without using the typical laminated El steel plates. Just some 💭
Pretty cool.
Very clearly explained and demonstrated. Thank-you. At those field densities, you're within an order of magnitude of the field strengths of superconductor electromagnets - and for a much smaller cost, in a safe manner, albeit within a much smaller volume of influence. You've gained a subscriber today.
Thanks!
If you can afford to reduce the volume further, two tapered, steel pole pieces in the shape of a pyramid or a cone can more than double this field strength.
@@TechIngredients Yes, it's an old idea which has been used professionally. I have a magnet which was rescued from a scrapped 1950's magnetron and which uses that technique to concentrate the field.
This is the most underrated channel on youtube.
