A refrigerator magnet is magnetic because it is a "permanent" magnet. An electromagnet is a magnetic field caused by a current flowing through a wire.

The term "refrigerator magnet" is ambiguous and may refer to any number of types of magnets. However, typically a refrigerator magnet is going to be relatively weak and made of the most inexpensive materials available. Hard refrigerator magnets are likely iron. Flexible refrigerator magnets are made of bonded ferrite powders; barium ferrite is among the most common. In general classification, a refrigerator magnet is a permanent magnet.
if a refrigerator magnet cant hold a piece of paper against a refrigerator, the forces acting on the magnet must be what?
the refrigerator is iron or steel, therefore the magnet sticks to it.

A refrigerator is not a magnet, however it does contain an electric motor, and within that motor are permanent magnets (as well as electromagnets).

The permanent magnet always retains its magnetism so even the smallest temporary magnets will stick to it. its uses will include keeping the refrigerator door sealed nice and tight as well as the actual door being a permanent magnet so pictures and notes to the kids can be hung on it.
A. Compasses typically use a permanent magnet.

No, it's a permanent magnet. It consists of an iron oxide, and iron is a permanent magnet.
They basically work just like any other permanent magnet. The magnet, and the magnetic material (iron-based) in the refrigerator, attract one another.
Yes, it is a permanent magnet.
