When you break a bar magnet into two pieces, you get _________________.

• two south poles

• a piece of iron that is no longer a magnet

• two north poles

• two north poles and two south poles

The picture below shows a piece of iron before it has become magnetized.  What will the domains (groups of atoms) look like after it is magnetized?

• None of the above.

• They will all line up in the same direction.

• Half of them will line up in one direction and the other half will line up in the other direction.

• They will look the same.
