Suppose we have a polystyrene ball measuring about 10 cm in diameter with a small rare earth magnet in its center, and we levitate this ball in mid-air using an electromagnetic field. There is an ant on the surface of the ball.
- Would the ant walk around the surface of the ball indefinitely until it dies of exhaustion?
- If there is more than one ant on the surface of the ball, would the ants cannibalise each other?
- Would an experiment like this be viewed as cruel?
- Where can one buy rare earth magnets?
