Nickel is one of four elements that are ferromagnetic around room temperature. Alnico permanent magnets based partly on nickel are of intermediate strength between iron-based permanent magnets and rare-earth magnets. The metal is chiefly valuable in the modern world for the alloys it forms; about 60% of world production is used in nickel-steels (particularly stainless steel).
Magnets are made from a rock called magnetite. For example we will take a bar magnet it is made up of tiny bar magnets, they are called magnetic domains.
