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? (That is, using electricity to power an electromagnet to generate another magnetic field)

Some searching gave me the equation for Magnetic Pressure and Electrical force, but I don't understand how to solve this problem.

A prompt reply would be appreciated.

Thanks!
