An iron nail does not pick up paper clips as a magnet would.
what can be concluded about the structure of the iron nail?
a. it has no domains.
b. it has domains that are not aligned.
c. it has domains that are aligned along the nail’s length.
d. it has domains that are aligned across the nail’s width.

B. It has domains that are not aligned.

Explanation:

When domains are aligned, object acts as a magnet and attract other magnetic objects.

Although iron is a magnetic material but it does not act as a magnet all the time. It is a temporary magnet. If it is not picking up paper clips, then it must not be magnetized. This means that at this time, the domains of the iron nail are not aligned.

they should be similar or the same
