Could a strong magnet field repel the body before damaging it? Could a magnetic field be strong enough to damage the body or erase the brain? Blood is slightly diamagnetic, so if the field was strong enough, could it repel a body evenly? Could a diamagnetic material go through electrolysis with water then ingested to give the body more diamagnetic properties?

A strong magnet can repel a body, but the effect is due to small diamagnetism of every atom.

You can see a picture of a levitating frog and a video here. And a very good explanation and more videos here.
