Lisa exposes an iron paper clip to a very strong magnet. She is now able to pick up other paper clips using her newly magnetized clip. What happens within the paper clip in order for it to become magnetized?

A) The magnet randomizes the domains within the paper clip.

B) Part of the strong magnet "rubs" off and joins to the paper clip.

C) The strong magnet aligns the magnetic domains within the paper clip.

D) The strong magnet creates an electric force filed around the paper clip.

Respuesta :

The correct answer is C

The strong magnet aligns the magnetic domains within the paper clip. In an ordinary iron paper clip the magnetic domains are present, but they are random, pointing in different directions. This cancels out their potential magnetism. When introduced to a strong magnet, the domains become aligned and begin to point in the same direction. This, in turn, makes the paper clip magnetic.
