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
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.
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
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
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!
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
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
Magnes N52 o wymiarach 29mm srednica i 29mm wysokosc podnosi podobne ciezary. Moze moznaby zbudowac cos co spowoduje wylaczenie naturalnego magnetyzmu magnesow stalych by nie zuzywac energi w trakcie podnoszenia?
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.
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.
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
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)
