Question

What type of magnetism is present in a magnet that you use to place a photograph on the refrigerator?

A. Induced
B. Superconducting
C. Contact
D. Permanent

Answer 1

D, Permanent

Step-by-step explanation:

Permanent magnets are the magnets you would use to put on a refrigerator.

Answer 2

The right answer is D. permanent.

Step-by-step explanation:

Permanent magnets refer to those magenets that exert an magnetic field due to their internal structure. That is, they naturally generate a magnetic field.

So, when we talk about magnets we use on the refrigerator, we are talking about magnets that naturally exert a magnetic field, due to their internal composition of the material that are made.

Refrigerator's magnets are not superconducting, or induced. There's no need of any electrical current to produce their magnetic field.

Therefore, the right answer is D.
