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.
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...
