Permanent magnet

A permanent magnet is a material that produces its own magnetic field without needing an ongoing energy source. This occurs because the tiny magnetic regions inside it, called domains, are aligned in the same direction, creating a persistent magnetic force. Common examples include refrigerator magnets and certain types of metal alloys like steel. Permanent magnets are widely used in motors, speakers, and magnetic storage because they reliably generate magnetic fields over time without power. Their durability and consistency make them essential in many everyday and industrial applications.
