If a person had enought helium balloons to make a magnet weightless, to counteract the force of gravity, then could you see it interact with the earths magnetic field?
Question Date: 2007-08-03
Answer 1:

If you use a compass and you are holding it up with your hand, That is essentially the same physics as using helium balloons to hold it up. There is no change in the interaction regardless. The laws of magnetism are the same with or without gravity.

Answer 2:

Yes. However, a simpler experiment would be to tie a magnet to a toy boat and put the boat in the water. If the boat isn't made too heavy by the weight of the magnet that it would sink, then the magnet will cause the boat to orient along the Earth's magnetic field lines. This, by the way, is HOW a compass works.

Answer 3:

Nope, this only makes a compass. That's exactly how they work.
