I know that a plane flying through the Earth's magnetic field perpendicularly will create a small voltage between the wing tips. The Earth's field is very small. If the plane were to fly through a large field, this voltage would be much higher. My question is, would it work if the plane carried a large magnet, and essentially provided its own magnetic field, or is there a fundamental problem with this plan that is related to the motion of the magnet? My physics class is curious to hear your comments.
Thanks!
