For this "simple" electromagnet, you'll need: thermo conductive grease and glue, double enameled copper wire, polycarbonate, a 3D printer, a TIG welder, and a lathe capable of machining steel. The aluminium heatsink is optional
@@ShopperPlug Sure. But just the fun it's worth it. Then if you can pay it selling parts, that's the perfect world. If you've got that opportunity, go for it!
Yeah, it's really simple presuming that one has a machine shop at hand. Next....he will build a "simple" HeAr laser using "just" a lathe, a mill, a TIG welder, glass blowing equipment,electric measurement tools, and some random stuff he just happened to have laying around.
Mezmorizing Brother. Fantastic work. What's really great about it is the lack of static noise from it. We've made a few from discarded microwaves but they buzz like crazy
amazing i might make a 3D printed one i dont need that much power and rigidity you need a free wheeling diode so you dont fry whatever is powering that electro magnet (every coil should have a diode) also plz insolate the wires more at 4:24 they might shot out when it gets pressed on or something ...
@@ilikewaffles3689 the magnetic field is generated on demand by the coil to magnetize the steel rod in the middle .... You apply power to the coil ,the coil magnetizes the rod and the rod will stick to metal ..... I only want to print the outer housing
very nice work. i wish i could make one too, but after buying a 5000 euro lathe, 800 euro worth of welding equipment, 1000 euro welding lessons, build a 15000 euro shop to fit the lathe and such, i think i would not have money left to buy the materials to make this...... Lol. nice video!
You don't need those things. You just need to try and want to make something. Repeat it thousand times and you will create something working eventually.
it’s amazing how powerful only 1 watt of power is, in terms of electromagnetic (attractive) force. I would like to make a very powerful electromagnetic for my most recent experimentation with the don smith rotating separator coil, research i am conducting. thank you for making this video, this is very educational, and extremely helpful to the greatest degrees of simplicity, and precision. Thank you!
EXCELLENT JOB! I assume you applied a DC voltage. Can you confirm that? Also, did you measure the resistance of the coil? Thank you in advance for your reply. Herman
I’m curious if there would be any improvement in lifting capacity per watt if bifilar-wound and trufilar-wound coils are used, all other things being equal?
well I'm no expert so i might be wrong but given what knowledge i have this would not work at all since the whole point of a coil is to make all the wire loop in one direction so that the magnetic fields produced in the wire add constructively and make a much bigger field, however if you used bifilar wound wire then your basically changing the direction of the windings of the coil half way since the current will flow in opposing directions on the 2 parts of the wire, this means that bifilar would basically shoot itself in the foot and kill almost all the magnetism and trifilar might approach, but be inferior to the magnetic pull of a single wound wire loop however if you used bifilar then the self cancelling feature would turn it so that you basically made a gate drive transformer, and a ridiculously big one at that, now you can drive a mosfet the size of a car battery lol
I've had much experience with winding electromagnets. One thing that would improve the power levels on the magnetic field ie the Gauss rating, is to take smaller wire find the total length you'll need to fully wind the bobbin. And divide that length by about 8 to 10 pieces. Solder them each at the ends and then rewind the coil. In my experience I was able to improve the Gauss rating by 350%, and have the resistance down to almost less than 1ohm. If you use a layered steel core compared to a solid steel core that will also improve the electromagnets power levels. It could just be mild steel or Supermendur materials.
Thanks! Turning a spool of polyamide on a lathe takes just a few minutes, the polyamide is processed like plasticine. For 3D printing, there would have to be supports to one flange, subsequent smoothing would take more time
We used to use mag drills on structural steel, basically a large, (maybe 30-40 lb?) drill press that cut 1" holes, with a 110 v magnetic base, had to put a chain around it in case someone kicked a breaker, magnet itself could hurt you too.

GREAT WORK!!!!!! I assume the power is DC, thus the Al outer casing won't be affected by eddy currents? If it was AC would eddy's come into play?? THANKS MUCH....I really need to get such equipment!!...milling machine, 3D-printer, welder... I think I would have put a couple pieces of heat-shrink where the wires go through. --dALe
Thanks! I gave a lot of epoxy there, the wires are practically flooded (not only that they do not touch the housing, it was also a protection against vibration and tearing off)
This is very very professional. The only thing I disagree is the size of the electromagnet. If I had those materials and machines I would make an 8" diameter weightlifting electromagnet capable of lifting hundreds of kilos. :D
I was thinking of the same thing because we are bound to lose a few magnet fishing! would that electric magnet work if it was submerged? thanks Ernesto.
a really great build, until i saw you didn't insulate those wires after soldering. that could end up shorting out. also, make one with a 20awg wire and put 10amps and as few volts as you can though is. more amps, less volts. makes it a lot more powerful. keeping it cool will also increase its power. but damn that thing is very professional looking. wish i could afford a metal lathe and tooling.
do you know of an inexpensive electromagnet that can be left turned on for longer than an hour? all the ones i see say 10 minutes or left or they over heat.

The most important tool he got is the lathe.
@@ShopperPlug and not a cheap one!
@@josepalacid I’m really saving up to get a nice solid lathe some day. I’m sure it can pay itself later by selling parts made from it.

Fantastic idea with the xt30 connector!
Very nicely executed. It further inspires me to get a lathe to do cool stuff like that. Thanks for sharing
why specifically the xt30 connector a great idea? clarify
Pretty impressive home made magnet - Thumbs UP!
Fantastic work, Maciej! Really well done! 😃
Stay safe there with your family! 🖖😊

Piekny projekt. Thank you for uploading this for all of us to appreciate:) (btw, it brings the meaning of "simple" to a new level!)
Very neat and cool project! 👍🏼👍🏼
Congrats, on your work it´s a beautiful piece to demonstrate how can build an electromagnet and test it. Thanks.
Awesome and very neat workmanship. Cheers.
What a clean design!
Very neat! Keep it up!
Great job, congrats.
Really nice job!!!
great job looks real professional
Nice presentation and workpiece congratulations 🥳 👍 thanks 🙏
Very nice and neat construction.
Great job, would you consider including a temperature sensor in the future? Could be used to avoid burn out
Nicely done. Complements to your build. 👍👍😊😊
Love these projects!

@@fortherest8490 yes
Don't u need a conductive surface in order for the magnet to work (i.e. not plastic)?

You should make a coil gun, that'd be cool

Yeah, right!
Yes
That’d be sick
@@franciscovilaca900 in a good way, right?
That's very interesting and it looks like it could be done in about a week with all of the material needed to complete it.

I really like simple projects.
Cool, I liked it! It’s very interesting how much weight it can withstand, check it with scales, I really want to know!
It is very cute. Also, it can be used for magnetic levitation with an appropriate controller.
Fantastic !
Nice design and build

Thank you for a very informative video. I always wanted to know how to make a good electromagnet rather than the crappy ones we made at high school.
Nice build...
What a great project and the work perfect. Do you have a idea of the maximum voltage and amp that you could put into the magnet ?
Well done !

Thank you for sharing the experiment
Excelente!!!

Question. Does a nicer winding of the copper thread makes a stronger magnet? I think nicer winding will fit more copper on the spool.
I've had much experience with winding electromagnets. One thing that would improve the power levels on the magnetic field ie the Gauss rating, is to take smaller wire find the total length you'll need to fully wind the bobbin. And divide that length by about 8 to 10 pieces. Solder them each at the ends and then rewind the coil.

If you use a layered steel core compared to a solid steel core that will also improve the electromagnets power levels. It could just be mild steel or Supermendur materials.
It's magic!
Great as always Maciej! can i ask why did you use polyamide instead of just 3d printing the coil part?

@@maciejnowakprojects or split the spool in half and then glue 🥰

Wondering what type of welder you yourself use for aluminum??
Excellent
👍🦘 Great video , thanks.
Amazing
is it possible to use both the faces if you drill all the way through ?
Great! Now make a tokamak fusion reactor.

Great. one little suggestion: should have insulated the solder joints, as they might short circuit though the whole metal body.
