There's been a change in plans... A while ago, I helped my Grandma by shoveling some mud out of her basement after it got flooded :P She gave me 2x 25 foot old extension cords. I took apart one for the wire inside for my experiments, turns out, the wire works great, the insulation isn't too...

Danke schön :smile: (Thank you in German)

Thanks for the tip :smile: Instead of buying a 100 ft. extension cord, I shall instead purchase 2 or 3 of those insulated wire spools that you spoke of, how would one word that while looking for it on their website?

I don't think you quite understand what I am going to do, I'm going to use a solenoid made from wires from an extension cord. I'm not going to use the Earth's North and South poles to magnetize my circular magnet, but instead, a very powerful solenoid wrapped around it.

So... possible? :D FYI: I don't need that much of the flux to escape the magnet, just a little tiny bit.

Why do you think a permanent magnet cannot be like this? With the round field and all?

So yes, I shall continue to reply after I purchase the extension cords, assemble the magnetizing device, and test the magnet, and then assemble my secret machine. When I'm done magnetizing stuff, I'll reply telling you how it went :D

Yeah, I can do that. (I already have a DC transformer that plugs into the wall, so that'll save a lot of time) This means the last piece of the puzzle is to buy the 2x 50-foot extension cords for about $20 :D And of course, a bunch of assembly that'll probably take a few hours :P

Thanks for that :smile: Are you sure just 12 volts would work? I do agree with the AC-DC thing, but I may need more voltage, but I don't know for sure :P So maybe instead of the light socket, I should use the DC transformer I mentioned earlier?

Recently, I was experimenting with a nail, a solenoid made from some sort of TV wire (I think), and a transformer for the 12V input. After a few tries, I made an electromagnet :smile: With this new knowledge about electromagnets, I have decided to purchase 2x 50-foot long extension cords (I...

Actually, the goal is to magnetize a magnet by changing the direction of the magnetic domains. Not to reverse them, or remove them, but altering their direction into a clockwise or counter-clockwise manner.

65 posts already! :)) :woot: ?:) :nb) :eek: :biggrin: I never expected this many on my simple questions! :P

I like your idea :smile: When I get to the point to test different materials, I shall do the cylinder thingy that you mentioned :smile: My plan... 1. Get a bunch of cylinder magnets of various ferromagnetic materials 2. Test them with solenoids, to find a good ratio of...

Well, hopefully it does :) I could try different materials until I find the correct one :) Preferably materials that are already magnets :P

Thanks, I think I'll try all of that stuff :D But for a magnet about 2-3" in diameter, made out of ferrite, or iron, or something else, how much "juice" (electricity) would it take to re-magnetize it?
