Can I just say, thank you for leaving in your mistakes and then working it out... its genuinely nice to see a fully honest video that shows its all... and I've seen a few of these posts and builds and this is by far the best 1 to watch and gain information from with a basic shown example of how to build this and make it work... Great job sir... 👏 👍 👌

[@SVSunnyJim]

I agree, very clear and concise.

[@Lucas-vk8fz]

Awesome explanation on how this actually works..thank you so much for that

[@johnlannikk2701]

Interesting part is the information about a closed and open path for the magnetic field. I had not realized that a closed path renders the magnet ineffective and that an open path seeks a way to close it. Thank You.

[@wallyworld817]

Actually it's because the magnetic fields are weakening one another they all have to be south up or north up.

[@Maxim.Teleguz]

@@wallyworld817 open path that wants to be closed is still a better explanation

[@wallyworld817]

@@Maxim.Teleguz not for me being that magnets when "attracting" or "repelling" they're really just trying to get to counter space the null the center of the toroid.

Mr Electron ......i would love to save and use a Hand Power Sander for sentimental reasons ! But it is 220v AC and we use 120volts in my region ! Is it possible to open the Sander take the small Transformer out and rewire it to work with only 120volts !! Can you explain if I also have to cut out the two 110 volts primaries assuming since it is 220volts !! What tyoe of guage cable should i use and how many turns will it have as the end result !! I believe this can be achieved easily by you !!! Thank You in advanced !

[@seansysig]

20kg is not a lot of weight. Would this work with a 120 volt microwave transformer?

[@serhatsarkus1738]

Hello. I used 12 volts and 12.5 currents. It got too hot after 20 minutes of operation. If I lower the current value, would I use it longer? Will I experience a decrease in my usage power? How much current should I use at most?

[@BarMagnet]

Should you back up your power supply's flywheel diode? That's a rather large inductance.

[@mabul513]

Do you think cutting it gown to primary would make it stronger? Or do you think its better with large surface area? Just wondering if there's more power if slots cut or chopping down to the copper level.

[@rayhamiltoncooper5416]

Hi electron could the magnet be used in water with dc battery would it need insulated from water

[@mabul513]

Cutting slots. ? Would that give more strength than cutting down to primary coil? Any answers would be helpful.

[@electronic7979]

Excellent idea

[@mabul513]

Cutting the slots would it make stronger if chopped down like on other clips or is this way better strength?

[@mabul513]

If chopped down to top of primary would the magnetic field be stronger? Or surface area better? School teachers anyone? Saw one go 500kg and hold with full mot but only top missing not cut out. 500 kg was max the scale went to. Cut down to primary or use the surface area slots cut?

[@KarlMiller]

Well done. Great explanations. What is the benefit of just cutting slots in the top instead of just chopping the whole thing in half horizontally?

[@prodigalson2670]

does it have to be DC for magnet to work or it can also be AC

[@TotoGuy-Original]

so you have to power it with voltage then disconnect the power for the magnet to become effective? i wasnt clear on this part great video by the way. i watched people make magnetic platform for a drill or something they didnt explain the science they just made it. your video shows it can be simple and not need mains voltage supply only low voltage high amp. tell me what is the ideal volts and amps to power this?

[@alphahelix91]

The 12 V cable is very thin fom the the dimmer cable in comparison to the trafo sheet. And the dimmer is not destroyed ? Emma crazy !

[@raymondgarafano8604]

This is what kids should be seeing in science class in school. , FOR REAL! to experience to pull of the magnet. it will not mean much to see a movie of it. nothing personal against this nice guy for showing us, what he did as I did too, I love this effing thing! any young kid in school science class that sees this will probably really get into science. It will open up their mind to how motors and generators work, by seeing how much magnetic force is needed to do a job and how that force is made.

[@Meta369]

Brilliant, well explained. Thanks.

[@qaisarawan93]

nice video I tried to follow along with it and bought a used MOT, the seller connected ac voltage to the primary winding (thin wire side). And it created humming sound. At home I removed that side and when I connected ac to the secondary side it created smoke and smell and became very hot to touch. Seems like the Secondary was already short? What you say? Also Now can i rewind it using suitable size enameled wire? Will winding it with slightly thinner wire be ok for spot welding? Current winding is using 0.9mm enameled copper wire and the length and breadth of cross sectional area is 15 by 17 mm..

[@mabul513]

Saw it pull 300 kiss and was max scale went to so wonder best way? Chop down? Cut slots. Or what would be best way. Idea of having larger surface area seems good but the shaved down one pulled 300 plus as never pinged off

Since the winding is designed to run under 240V AC, why not connect it to 240V AC directly? Would it burn up while the magnetic circuit is incomplete?

You must use DC current. Plugging into AC wall socket will not work.

[@AamirAli-ws1rt]

Primary some wire accidentally cut Can you use the transformer ?

[@forestdenizen6497]

The effect causing the spark is called "back emf." It is a big deal in industrial motors as it can destroy control and power gear if not properly handled. Also used in some fluorescent light starters.

[@nazgullinux6601]

Back emf is what laymen and ignorant chodes call it. The properly learned know it is called inductive reactance.

[@mabul513]

Is it stronger to fill the spaces with steel and pushing primary up with slots more surface area if cut outs also flat surface but other clips the cut them to coil? Anybody know best way to get full effect. To slot or cut down to the coil? If wanting a table clamp for milling whats best way to do it? Chop off to coil or push up coil and cut slots keeping larger area and then would fitting steel underneath to fill the airbag? Any physic teachers who can say chop down or push up coil and do what with space below?

[@ricardogutierrezrocha1752]

Do you need to connect it to DC voltage? Or can you connect it directly to AC voltage?

[@fuorman4872]

ac only

[@jamescampbell7823]

Not only does DC power it just fine but DC works much better AC should not be used for electromagnets in my opinion because it switches the poles continually and is therefore much less powerful at least from what I understand and certainly from what I've seen. Not to mention that DC give me warm fuzzies and AC makes me distrustful of any exposed wires, which describes the secondary winding to a t. and then it's a magnet so it's going to attach to other big pieces of metal which sounds to me like a hell of a way to get a shock. Plus you get that annoying buzzing sound with AC

[@stavrosps1238]

@@kamisama9715 Thanks.

[@maurizioaurora7578]

I think that it's not a good idea. The strenght of the magnetic field depends on the amperes you send on the coils and the number of coils; with a smaller wire you can make a lot more coils but you can't have the same current for 2 reasons: 1) smaller diameter -> way bigger resistence (resistance depends both on diameter and on lenght, and you are making it way longer with smaller diameter) 2) even if you bump up the voltage a lot to have a good amount of current in that wire remember that the total current a wire can sustain depends on it's diameter, and since you are making it smaller it will overheat and break very fast. For this reasons you usually want the wire as thick as possible.
