blackmajor93 he used microwave transformers and it didn't look like he had much wire in the coils. It lifted more than I expected. I can make an electromagnet with a nail, some wire, and a battery; that doesn't mean it will pick up an I beam. Don't be condescending.
John Fraser I made one with my 9yo boy yesterday from one transformer. That thing is much, much more powerful than I expected. Only thing is it get super hot after a few seconds. What voltage do yo recommend?
Came here expecting another 5 minute crafts type project, didnt expect something that is actually useful. I didn't believe in the slightest that it would be that strong either...
As I already said you are doing a thing which is an entire industry does with the help of designers, engineers, CAD designs, prototypes and CNC perfection but you all did it like building a Lego toy. God gifted you great knowledge and resources.
Yes. I showed this to my 6th-grade students. I kinda skipped some of the unnecessary making part so that they can focus more on the video. They really enjoyed watching it, and especially loved the ending part where two men do lots of experiments with the electromagnet!
Yes as the coil turns magnetic, it heats and repeated contraction and expansion will result in it being separated from the steel top as the cofficient of expansion for both resin and steel top varies. to make it stronger, consider welding a steel plate to the top one.
@@richardmoeller5351 actually they removed a coil and a big part of the core so the reactance is lower. this thing is probably drawing ludicrous amounts of current and probably heat up real fast (unless he powers it with current limited dc)
Couple of suggestions: If you ever drill a hole, get a countersink in your battery powered drill and get rid of those sharp edges around the holes. And if you ever put a cable through a part like that, put a strain relief there, the typical go-through-plate reliefs also provide protection from the wire abrasing against the plate.
You guys are insanely brilliant. The stuff you make and the way you make it look easy is ridiculous. Make a fricking spaceship, seriously. I know you can do it
I have seen a few of these transformer type pickup magnets, but I give you a thumb up for shortening the TRF core for further reducing magnetic circuit resistance.
@@rossyb_youtube AC would be much worse than DC because you have to imagine that with DC the charge moves in one direction and this movement creates the magnetic field which points either up or down. With alternating current you force the magnetic field's direction to change all the time and this creates a loss of power which is proportional to the frequency of the AC.
@The Great Cornholio but therefore you would need to connect it backwords - also now the plug is delivering the voltage that's means it would be possible to touch a live contact (if its just 12v as i think it wont matter)
Hey! This video makes you once again reconsider the value of broken microwaves! Awesome job dude, could you tell us how many amps you're throwing into that baby? And a happy new year!
I made one with 5 trans and it was still cool after 10 hrs operation. EM force produces very small amt of heat. The heat gets dissipated through the casing metal.
each of the transformers from the microwaves has a positive and negative. He just attached each of the positives and negatives together then fed them into the main female plug. which plugged into a male adapter which probably gave out the same power as that of a house socket.
@@inrg3688 It will not pick items up due to mains (in us) being 60hz, which means that the direction of current changes 60 times a second. Because this means that the polarity of the electromagnet will change 60 times a second, it will not pick items up like shown in the video
You guys should make a super powerful Blender out of a 5 gallon bucket. ha. Something that would blow the Vitamix and Blendtech out of the water. You will need something like that for parties. Just saying
Robert Monroe The iron body is a heat sink and wouldn’t allow enough heat to harm the copper you dumbass... as far is that female plug you’re talking about yo ass is just fantasizing about a bitch with a strap on!
@@luciustate4386 Strange statements, but now I see about you are thinking all the time. Strapons and ass, you see it everywhere, poor. Somebody did a violence with you in such a way?
Awesome project! The uses for old MOTs never cease to amaze me... What is the total capacity of it? It's obviously enough to life both you guys & a heavy plate of steel, but did you test to see just how much it would hold until it fails? (Small car?)
If you touch 24V DC it is completely safe. But not safe for the power supply itself as it can get shorted by literally anything from metal that touches it
I like what you've done here. I'm really surprised by how powerful that thing is, I expect it'll serve well in the shop you're making. May I just say, though, that using a zip cut, without a safety guard, without gloves, and without the workpiece secured, is just an accident waiting to happen.
You've got great hands man! That looks professional! Seeing how you salvaged those parts from a microwave and made this tool reminded me of those Discovery channel prehistoric shows with cavemen - but in a more recent form, lol. GJ
Sergey Sorokin thank you, do you know how to make a power supply for this, as soon as i hooked it up to my dc wall outlet power supply it fried my powersupply
Nice work, I applaud you for that, but I hope you can explain to us the electrical circuit it uses, the strength of the voltage, and can I use it for a long time?
очень аккуратно сделано, достойные проекты у автора, но как иногда говорят в рунете, тема сисек не раскрыта) how many does it can lift? how much is voltage supply?
Great video. Can I suggest you add spare power source, like a pack of 2*D size batteries. In case you suddenly have a power surge, you still can hold the steel.
and yet another cool project by you guys!!! I enjoyed watching your videos and I don't mind saying that I use a lot of your ideas. please keep the videos coming our way
1. What is the biggest weight in kilograms which can lift this electromagnet? 2. What is voltage: 110 V, 220 V or 230 V? 3. What is the name of green liquid substantion, which was used for filling the steel bowl? Thanks for answers. This device looks interesting.
Very ingenious project. I never thought a used microwave oven component has so much use. Like this you have any project using damaged inkjet printer motors?
In case of reproduction: fuse it, ground the plate housing and make sure that the welding and the epoxy can handle the stress made by these huge forces. Btw nice video!
