Construction of a simple electromagnet from 3 different shafts and a copper wire

[@josepalacid]

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]

The most important tool he got is the lathe.

[@josepalacid]

@@ShopperPlug and not a cheap one!

[@ShopperPlug]

@@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.

[@josepalacid]

@@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!

[@kalleklp7291]

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.

[@waynebarrow2517]

Pretty impressive home made magnet - Thumbs UP!

[@jameshaynes8190]

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

[@TrasherBiner]

why specifically the xt30 connector a great idea? clarify

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

Piekny projekt. Thank you for uploading this for all of us to appreciate:) (btw, it brings the meaning of "simple" to a new level!)

[@loricastro3772]

Nice job, thanks for sharing!

[@willemkossen]

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!

[@fupidox5642]

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.

[@fouzaialaa7962]

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 ...

[@fortherest8490]

Yes post it on your channel and it would be awesome

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

[@fouzaialaa7962]

@@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

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.

[@bulentvural2554]

It is very cute. Also, it can be used for magnetic levitation with an appropriate controller.

[@mastopage3120]

The lathe. The only tool that can make itself.

[@jigsaws02]

Great as always Maciej! can i ask why did you use polyamide instead of just 3d printing the coil part?

[@maciejnowakprojects]

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

[@ilikewaffles3689]

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

[@RadiantFreeEnergyResearch]

it’s amazing how powerful only 1 watt of power is, in terms of electromagnetic (attractive) force.

[@TRabbit1970]

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?

[@olyve4167]

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

[@harnesswinergy9785]

[@JL-vg4bm]

I dunno bout anyone else but for me, the word SIMPLE got run over when you pulled out the lathe. haha

[@maheshdhameliya2089]

Nice 👍

[@matteedstrom]

Question. Does a nicer winding of the copper thread makes a stronger magnet? I think nicer winding will fit more copper on the spool.

[@woodbrassandglass]

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.

[@toranga997]

May i ask what kind of a steel bar did you use here 304,303,316L or 420 type? also what are the dimensions of inner part and center thanks regards

[@vdsgma]

How much voltage and amps?

[@warrenpeas]

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.
