- Magnet - Wikipedia
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 creates its own persistent
