Ah, thanks. So it has to be a solenoid, and one with a huge diameter, too. Let me see if I understand your point. 10^9 Amperes * 100 meters^2 * magnetic field of Earth (50 microTeslas/5000km) = 1 Newton of force Because I want to use a 25-meter^2 area loop, I can just multiply the Amperage by...

OK, let's clarify some things here. MFB, thanks for the recommendation; For the time being I'm just trying to prove how ludicrous it is to do it without the superconductors. I'm getting a result of about 5.7*10^7 Amperes required to counteract a gravitational force of 1765 Newtons, but I'm not...

*shrugs* Uh, does it affect my calculations?

Riiiight, silly me. Given that I'm calculating for a charged piece of flat metal, not a solenoid, do I need to modify the equation F=IBL Or can I just get rid of L?

Thanks guys, a ridiculous number is what I'm looking for. Could you use electrostatic forces to levitate instead and would it be more efficient?

OK, this'll be my first post here. I was writing on a topic about magnetism when I realized that I simply don't know enough to answer the question effectively. The question is, How much energy does it take to magnetically levitate a 180.0 kg mass using the Earth's gravitational field...
