Question

if a magnet is broken into two pieces, what happens to the magnetic poles?
one piece will have a north pole, while the other piece will have a south pole.
each piece will still have a north pole and a south pole.
each piece will have only a north pole.
both pieces will no longer have any magnetic poles.

Explanation:

A magnet has a north and south pole. When broken, each piece becomes a smaller magnet, so each still has both poles. The first option is wrong as both pieces need both poles. The third is wrong (needs both), and the fourth is wrong (magnets always have poles).

Answer:

B. Each piece will still have a north pole and a south pole.
