Hey!
I am trying to get a rough estimate for the B-field (from a electromagnet) required to levitate a train.
Assuming the train is of mass M, the force required to lift it and hold it at a distance D would have to equal M x g right?
But how do i estimate the b-field an electromagnet would have to generate to make this happen?
Thanks for any help!
