Question

what type of magnetism is present in a magnet that you use to place a photograph on the refrigerator?
a. permanent
b. contact
c. induced
d. superconducting

Explanation:

A magnet used to place a photograph on the refrigerator has its own magnetic field without the need for an external magnetic field to induce magnetism. Permanent magnets retain their magnetism over long periods. Contact magnetism is not a standard type in this context. Induced magnetism requires an external magnetic field to create magnetism in a material. Superconducting magnetism is related to superconductors and is not relevant here.

Answer:

A. Permanent
