A permanent magnet made of an alnico alloy. It has a relatively strong magnetic force among magnets in practical use, but its coercive force is not very strong. It is used in speakers and electric guitar pickups. The name comes from the initials of its main components: aluminum (Al), nickel (Ni), and cobalt (Co).
