This link shows a powerful superconducting solenoid using the diamagnetic properties of frogs and organic materials to balance out gravity. The explanation says that it suspends them by pushing each atom up at the same rate gravity pulls it down to create weightlessness, or the illusion of weightlessness.

So, In zero G this could push a frog out of a powerful solenoid sort of like a coil gun. Or one could cover the aperture of the solenoid and the frog could be pushed against the floor at one Gee. Therefore a large bore solenoid could hold a man in simulated gravity. Granted this would have limited usefulness as the magnet would have to be absolutely huge and the person could probably only stand in it, so they would probably only be able to sleep and rest in 1 Gee. However, think a 16 tesla bitter magnet could redirect most cosmic rays and perhaps help as a magsail, though its usefulness would be limited by the lower surface area. So if you are bringing a large magnet with you, this might be an acceptable way to keep up your astronaut's strength. Of course if you only wanted to simulate Martian gravity that magnet wouldn't have to be as big.

The strength of a magnetic field falls off with the square of the distance, so making one powerful enough to fit a human in would be insanely powerful for 0.1G much less 0.3-1.0G. A magentic sail would use a magnet with a different geometry anyway.

A Frog Gun?
Cool!
