Two objects are near a bar magnet. One is about 1 cm away, while the other is 6 cm away. Compare and contrast the magnetic force that affects each object.

A magnetic levitation or maglev train rides rails without touching them. How does this work? Include the appropriate magnet drawing in your answer.

Please let me know if any formula is there that has power and momentum

This is based around gravitational potential energy and kinetic energy but I have no clue what to do.
