Making a Powerful Electro Magnet from a Transformer

Yet another use for an MOT transformer! In this video, I'll show you how to select the right transformer & converter it into a powerful electromagnet.

One main reason I keep enjoying your projects is that you do a great job explaining step by step process involved even in the most basic things. Great job sir.

Not sure if someone has already pointed out this minor detail, but I will go ahead and do so: when he drew the magnetic field lines for the transformer after being cut in half, the field lines should have actually gone from the middle section out towards the two open ends of the transformer at the bottom, not towards the closed end of the transformer on top. The vast majority of the flux goes in and out of the open ends, not the sides or top. You will notice this if you try to stick some iron on the top of the transformer- it will not stick nearly as well as on the open ends at the bottom. Very cool video though, and nice way of illustrating things!

Very impressed👍When testing heavy loads, make sure to insert safety link in both directions (use slightly loose rope), if the magnet fail at 300kg or more, the steel block will hit the car and the magnet can hit you with a great force, be careful!

Grinding, drilling, clamping, mill work, dent pulling, project or heavy material transfer, lock and that is just off the top of my head. Great video

Enjoyable video, I wish my Electrical Engineering tutor at college 60 years ago had, your interesting approach about magnetic flux.

Very informative video and it gave me great info on which type of voltage/current to use. Here's a project that I'm starting to work on. I go prospecting for gold out here in Arizona and we have a lot of " black sand " in our good paydirt. I'm taking a 4" pvc pipe and going to tape/strap 2 of these on either side to pour the dirt through so the magnetic field will "stick" the magnatite ( black sand ) to the sides and let to paydirt fall through for further processing. Challenge is to build one of these and post a video. Thanks again and I'll post pics when I'm done.

Something about this dude just makes him enjoyable to listen to and learn from.

Good to see that I am not the only one obsessed with magnets!

I couldn't help myself - I made a video on my channel several years ago. You have given me a few more
I have several microwave transformers that might be taking on a little transformation themselves 😁

Next term I will be teaching night classes on automotive electrical subjects. I drag around a rolling trolley with heaps of wire and you guessed of permanent magnets as well as electromagnets to show students how solenoids, motors, relays and other tricky electrical components work. I usually use a rotor out of an alternator as an electromagnet to show magnetic strength holding a solid shaft of steel, but your idea might be a good alternative (excuse the pun) option!



Keep up the good work! 👍

Great and useful project. I'm a woodworker with a good quality cabinet saw. I use two electro magnets in a wooden feather board to guide my work through the saw instead of using my hand (for obvious reasons), I can position the feather board anywhere on the cast iron table to fit the work I am cutting. I wished I had seen your vid before I purchased the magnets from Aliexpress. Going to build your drill press vice next.

Keep reducing the power supply to the magnet ( volts and amps equally ) to see at what point it fails at 300 kg's, then find your wattage from that and divide it by 300 kg's to see your watt strength in Kk's lifting power. Great video, well made and informative, would never have guessed that a low resistance in the system would make such a difference.

I will use it to load heavy pieces of steel Into my lathe and mill with my jib crane. Awesome video with how to and verification! New subscriber!!

Put different sized nails into different types of soft and hard woods at different depths and see if you can devise a practical electromagnetic nail puller.

I've watched two videos on magnetic vices. One created a "magnetic table" that holds the work with the vice mechanically attached to the table. The other used the magnet to hold a traditional type vice to the table. Both have advantages. If you want to get really creative you could try removing the other side of the core as well and see if the drill press table would work as one side of the core making a magnetically held magnetic table. 😎

Everyone else on the planet would've drawn the magnet on the whiteboard with North on top. Not a Kiwi!.. Great vid, long time sub. Keep 'em coming!

[joejane]

thank you for not blaring music thru-out video
wonderful explanations

[iamwillwatson]

+ 1 vote for next video to make a magnetic chuck or vise!

[teddysoft]

Thanks for going thru the steps with a slow/easy understanding informativ learning 💪

[yeshecan]

Really...you do have very professional welding skill. Thank GOD ....yes you do have! 😇

[jeandeverchin]

Magnifique Monsieur. Merci pour la vidéo.

[LawsForever]

A very good combination of theory and application, well done!
One thing though: with a cut up transformer, the vast majority of the magnetic field lines go from the center bar to the side poles, not around the transformer (9:32). That's what causes the field loops to be closed when an metal object goes across.
