question 23 of 25
which of the following would cause an increase in the magnetic force between two magnets?
a. decreasing the separation between the two magnets
b. increasing the separation between the two magnets
c. decreasing the amount of excess charge on the first magnet
d. increasing the amount of excess charge on the first magnet

Explanation:

The magnetic force between two magnets is inversely - proportional to the square of the distance between them (similar to Coulomb's law for magnetic poles). Decreasing the separation distance will increase the magnetic force. Charge is related to electric fields, not magnetic force between magnets.

Answer:

A. Decreasing the separation between the two magnets
