Question

which statement best describes the magnetism shown by a paper clip when it is attracted to a bar magnet close by?
a. it occurs when touching another magnet.
b. it occurs when its near another magnet.
c. it occurs when there is an electric current.
d. its always occurring.

Explanation:

A paper clip is a ferromagnetic material. Ferromagnetic materials can be magnetized when in the vicinity of a magnet. This is called induced magnetism. Option A is incorrect because touching is not necessary; being near is sufficient. Option C is about electromagnetism (related to electric current), which is not the case here. Option D is wrong as paper clips aren't always magnetic. Only when near a magnet (due to the magnetic field of the bar magnet inducing magnetism in the paper - clip) does it show magnetism.

Answer:

B. It occurs when it's near another magnet.
