question 12 of 25
what happens to the domains in this iron nail when the south pole of a magnet approaches it from the right?
a. all the arrows align to point right.
b. all the arrows align to point up.
c. all the arrows align to point down.
d. all the arrows align to point left.

Explanation:

When the south - pole of a magnet approaches an iron nail, the iron nail becomes magnetized. Opposite poles attract. So the end of the iron nail closest to the south - pole of the magnet will become a north - pole. The magnetic domains in the iron nail will align such that the north - seeking ends of the domains point towards the approaching south - pole of the magnet, which in this case means they align to point right.

Answer:

A. All the arrows align to point right.
