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.
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
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.
You can build this electro magnet in all other dimensions with parts you maybe have laying around this just shows the principle of electro magnetic power
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
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
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
The diameter of the centre steel shaft is key to performance. If too big, there'll be insufficient windings. If too small, the magnetic field will saturate and limit lifting capacity. An engineering optimisation could potentially increase performance substantially
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.

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
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! 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)
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.
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
You need no seperate aluminium layer for the fins. Just bring the fins on the steel body. The thermal conductivity in the material would be much better cause there is no layer of thermal paste.

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.

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

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

Congrats, on your work it´s a beautiful piece to demonstrate how can build an electromagnet and test it. Thanks.
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. 👍👍😊😊
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.
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 ?
I really like simple projects.
Nice work. 💯👍🏻👍🏻

It is very cute. Also, it can be used for magnetic levitation with an appropriate controller.
Wow. So "simple" 😄👏🏻
Nice job, thanks for sharing!
Nice presentation and workpiece congratulations 🥳 👍 thanks 🙏
What a clean design!
Very nice and neat construction.
Cool, I liked it! It’s very interesting how much weight it can withstand, check it with scales, I really want to know!
NIce craftmanship!
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
Yes he used DC
Excellent work. Can you create a mini adapter kind of electro magnet that can be connected to a mobile 3.5mm jack ?
Awesome and very neat workmanship. Cheers.
Great video! Thanks for the detailed information!
great job looks real professional

jakiego kleju używasz do klejenia plastiku/ metalu?
The lathe. The only tool that can make itself.
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.
Hello! Which tool did you use to do the first frontal groove? Is it suitable for a CNC machine to produce 2000 pieces a month? Thanks.
Very neat and cool project! 👍🏼👍🏼
Nice 👍👍👍
constantly on momentary switch would make a nice in line trigger?
How many turns did you have on that spul?

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

Great! Now make a tokamak fusion reactor.
Wondering what type of welder you yourself use for aluminum??
Awesome! But those have to be the scratchy sounding napkins I've ever heard in my life. LOL
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
Less manual types like me who has a limited tool selection just converts a small or large transformers. All the hard work is already done for you. LoL
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.
is it possible to use both the faces if you drill all the way through ?
Great. one little suggestion: should have insulated the solder joints, as they might short circuit though the whole metal body.
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)
What are those special drill bit's your using ?
thanks
no waay! superb.
Very neat! Keep it up!
I would like to know how much ? And I need 10 of them!
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.
Voce vende isso aí ou é só pra demostraçao? Voce deveria vender tambem.
Great as always Maciej! can i ask why did you use polyamide instead of just 3d printing the coil part?
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
@@maciejnowakprojects or split the spool in half and then glue 🥰

Can it draw a piece of metal through a glass 3-5cm thick?
Can you use AC current or not?
good job buddy👍
Thank you for sharing the experiment
I was attracted to the video - it must be the metal plate in my head...
Why just 1W, what happened if you increase to 10W? Does it lift more?
I love your videos!
How much voltage and amps?
Very nice and professional looking work. But I would definitely leave “simple” out of the title.
GM can you make one of these up for magnetic fishing and a video showing the results
You need no seperate aluminium layer for the fins. Just bring the fins on the steel body. The thermal conductivity in the material would be much better cause there is no layer of thermal paste.
There's no need for cooling fins at all. If there was, it would be because of too high wattage to the magnet.
A magnet switch that is remote controlled? I never seen that and it would be great for magnet fishing
These kind of magnets are highly used in the fabrication industry, to lift heavy steel. Usually controlled by a crane, of some sort.
What is that polyamide is it kind of metal?
That would be cool on car shock absorbers to change how soft or hard the ride is
Just so you know any interference fit on the heat sink would actually transfer more heat than the glue
how you know many volts that your power supply gives i will be running it on 12v
Spectacular Electromagnet !!!!!!!!!!!!!!!
Why not use soft iron for the core instead of steel?
Hello mister very good job well done my friend
great. just amazing!!!
Excellent
Nice! Robert-Murray Smith discovered this phenomenon on his channel too!
