I was thinking that when I used an iron weight for the magnet, but it seems that I might want something more pure, so I'll probably change it out anyway. However, according to what you've said, that shape still seems to be right.

That makes good sense, thank you! I guess I need to find a very long piece of iron now I suppose.

As of now, I am NOT using a battery that charges. I actually am using some lousy Duracells, and, though I'm not proud to say this, a car battery, which was what proved to be so hot. However, would you recommend that I DO use a charging battery? I'm guessing that if I did it could probably also...

I do know the equations that I need to calculate this stuff with Ohm's law and the like. Sorry that I wasn't very specific about some things. Basically, I haven't been told much, but I believe that I must pick up a 2kg piece of metal, and it appears that I have been going about it all wrong. So...

I've had some bad trouble trying to create an electromagnet, so I've come here in hopes of help. Basically, I need to create an electromagnet strong enough to lift 2kg of weight. Because I don't know much on the subject, I have attempted this by wrapping insulated copper wire about an iron...
