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.
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
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.

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
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
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!
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 need exactly this electromagnet for my project. Can you sell me the very one? It has to be 12v and very strong. Size, more or less the same, even slightly bigger. How do I contact you for further details?
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 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
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
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.
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.

@@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
You should make a coil gun, that'd be cool
Really right
Yeah, right!
Yes
That’d be sick
@@franciscovilaca900 in a good way, right?

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

Great job, would you consider including a temperature sensor in the future? Could be used to avoid burn out
Fantastic work, Maciej! Really well done! 😃

Yes he used DC
Cool, I liked it! It’s very interesting how much weight it can withstand, check it with scales, I really want to know!
Nice wow
I would like to know how much ? And I need 10 of them!

"Making a Simple Electromagnet"
AMAZING!! Thanks for sharing! Greetings, from Salem, Oregon U.S.A.!! 🌲🌲🌲🌲
Please don't use the word "simple!" There's nothing simple about it!
It's literally wire around a magnet core are you slow?
What the heck of word "simple"
Great! Now make a tokamak fusion reactor.
jakiego kleju używasz do klejenia plastiku/ metalu?
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.

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

Mi ricorda l’esame di quinta elementare quando ho portato un campanello elettrico auto costruito con elettromagnete.
Wow. So "simple" 😄👏🏻
Nice presentation and workpiece congratulations 🥳 👍 thanks 🙏
Amazing!
How many turns?
Which length of copper wire?
I really like simple projects.
my job is sculpting. Nice to have you visit the youtube channel. Wish you success in life. ❤❤❤❤❤❤❤❤❤❤❤❤❤
How much voltage and amps?

Piekny projekt. Thank you for uploading this for all of us to appreciate:) (btw, it brings the meaning of "simple" to a new level!)
you need more bigger :D
Excellent work. Can you create a mini adapter kind of electro magnet that can be connected to a mobile 3.5mm jack ?
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
The aluminium heatsink can be eliminated and the steel pole piece machined with grooves. No advantage to having the aluminium there.
I wish I had a lathe. I could probably make one. I just don't have the space.
Tell me how this is simple!!!!
Dude got a whole metal shop.
Show me something good I can do without all that sh#%@
Excellent
Videos like this are just an excuse to use the lathe. Otherwise its impractical and expensive to make ot that way.
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.
👍 GOOD IDEA
👎 IMPRACTICAL DIY
SHOW SOME PARTS WHICH ARE MUCH MORE EASIER TO USE + AVAILABILITY
SO , SORRY , CAN'T LIKE JUST NOW .
Efekt końcowy jest fantastyczny 👍Taka mini sufnica na elektromagnetyczny uchwyt to przyszłość .Zawiesia hakowe powoli odchodzą w przeszłość.
hmm...
Very nice and neat construction.
Great video! Thanks for the detailed information!
-+2W for 20KG power is not bad.. :)
cool
I was attracted to the video - it must be the metal plate in my head...
Just so you know any interference fit on the heat sink would actually transfer more heat than the glue
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
Very nice and professional looking work. But I would definitely leave “simple” out of the title.
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
You call this simple 😂😁😁 nice work
How is that simple? You have $10,000 worth of tools. I can buy one for $25.00..
How many turns did you have on that spul?

Should have showed the voltage increased holding the scooter and the will and the pipes ,,,, video tho
Sir can you say how much power is required to take 20kg load.. 🥺
Respect from Egypt Man
Beautiful work
I would say it’s elegant, not simple😂
wow i didn't know u are polish
I like this but I would not call it simple!
I just noticed that that's DC. How the heeell?😳 Thought you needed AC for this stuff.
No, electromagnets are DC. AC won't work.
@@neatt3815 ac is the best

Can it draw a piece of metal through a glass 3-5cm thick?
The title says simple! I guess I should go buy a metal lathe to make a magnet. WTF
how you know many volts that your power supply gives i will be running it on 12v
Nice 👍👍👍
Congrats, on your work it´s a beautiful piece to demonstrate how can build an electromagnet and test it. Thanks.
Now make it bigger and strap it to a van to destroy police evidence.

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.
Okay class, notice how he uses the word "simple"
HAHAHAHAHAHA
The lathe. The only tool that can make itself.
Great Video , have you supplied 12v power?
Wondering what type of welder you yourself use for aluminum??
is it possible to use both the faces if you drill all the way through ?
constantly on momentary switch would make a nice in line trigger?
Amazing
What are those special drill bit's your using ?
thanks
Simple with thousands of $ of equipment
Hi how can I make one with hole in center to take bearing.
Awesome! But those have to be the scratchy sounding napkins I've ever heard in my life. LOL
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.
Voce vende isso aí ou é só pra demostraçao? Voce deveria vender tambem.
