Permanent Magnet

A permanent magnet is a material that can generate a magnetic field without the need for an external power source. It retains its magnetism over a long period of time, hence the term "permanent." Permanent magnets are commonly made from materials such as iron, nickel, cobalt, or certain alloys. These materials have their atoms aligned in a way that creates a strong magnetic field. Permanent magnets are used in various applications, including electric motors, generators, speakers, magnetic storage devices, and magnetic separators.
