How are magnets formed
A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc. and attracts or repels other magnets. A permanent magnet is an object made from a material that is magnetized and … WebIt can even become a permanent magnet if exposed to the right magnetic fields. This was an invaluable property for early humans and navigation. It’s thought that naturally occurring magnets formed from magnetite were how humans originally discovered magnetism. The Lodestone. A naturally occurring magnetite magnet is generally called a lodestone.
