What are the four properties of magnets?

Content Curator

A magnet generates an invisible magnetic field. The magnet produces a force that attracts or repels other ferromagnetic elements such as iron, steel, nickel, cobalt, and so on.

Properties of Magnets:

Magnets attract ferromagnetic materials.
The magnet's similar poles repel each other, whereas the opposite poles attract one other.
A hung magnet always comes to rest facing north-south.
The magnet's poles are arranged in pairs. i.e. magnetic monopole doesn't exist.
