what are three differences between magnetism and static electricity?

Answer 1

Re answer 1, static charges can produce an attraction or repulsion force. That's how an electroscope works.
One big difference between the two is the fact that the electrons are moving in a magnet and stationary with static electricity. As a result, static charge requires current only while building up a charge and constant voltage at zero current to maintain it, while electromagnetic field buildup requires voltage only while building a field and constant motion of charge or constant current at (ideally) zero voltage to maintain it.

Answer 2

1) In magnetism, the electrons are inside an object, with static electricity, the electrons are on the outside of the object.

2) In static electricity, the electrons can move to another object.

3) Magnetism can attract other object, static electricity cannot.

Answer 3

both forces obey the inverse-square law.
