What type of magnet is a fridge magnet?

Turns out that a refrigerator magnet is a Halbach array, which is a special arrangement of magnets that uses superposition to strengthen the magnetic field on one side of the array while cancelling the field on the other side.

What force does a fridge magnet use?

Is a refrigerator magnet a permanent magnet?

A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field. An everyday example is a refrigerator magnet used to hold notes on a refrigerator door.

Is a refrigerator magnet an electromagnet?

What are the 4 types of magnets?

Permanent Magnets. There are typically four categories of permanent magnets: neodymium iron boron (NdFeB), samarium cobalt (SmCo), alnico, and ceramic or ferrite magnets.

Why does a magnet stick to a fridge?

The magnetic field created by the fridge magnet aligns the spins of unpaired electrons in metal atoms in the fridge in such a way that the magnet and the fridge door are attracted to each other; this force keeps the magnet stuck to the fridge.
