A magnet is a substance or item that generates a magnetic field.
This magnetic field is invisible, but it is responsible for a magnet's most remarkable property: a force that attracts or repels other ferromagnetic elements such as iron, steel, nickel, cobalt, and so on.
Properties of magnets:
These are the magnet's main qualities:
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.
