B. When there is another magnet close by.

C. When there is an unused battery close by.

D. When there is a coil of copper wire close by.

b i think so because it makes senes

When there is another magnet close by.

Explanation: The needle of a compass is itself a magnet, and thus the north pole of the magnet always points north, except when it is near a strong magnet. ... When you take the compass away from the bar magnet, it again points north. So, we can conclude that the north end of a compass is attracted to the south end of a magnet.

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
