A magnet is an object that creates a magnetic field and exerts a magnetic force. The magnetic field formed in magnets is due to ferromagnetism. In ferromagnetism, the magnetic dipoles of atoms within a material align in the same direction, this is called exchange coupling. Due to an external magnetic field, the dipoles stay aligned and a magnet is created.
Domains or dipoles can easily be disaligned if the ferromagnetic material is exposed to heat or dropped on the ground.
