ball with magnet just in the middle bouncing on an iron surface that the magnet is attracted to..what happens on ground?..what happens in space?

ball as in like a bouncy basketball

Come back when you are sober.

the pull from the magnet when the ball is leaving the surface will cancel the "push" from the magnet while the theball is approaching right? so no funky effect at all?

not even with magnetic shielding?

>> No.9542400

does gravity do no work aswell?

Magnetic fields are created by either moving electric charges (i.e. current) or magnetic dipoles (such as atoms/bar magnets). In the case of current, it takes energy to create a potential which drives current. In the case of magnetic dipoles, the dipoles are formed by other forces which cause positive and negative charges to separate.

Work is equal to force times distance, so yes, gravity does work. Magnetic fields don't do work because magnetic fields need to powered by other things, which is what is really doing the work.
