Magnet

A magnet is an object that produces a magnetic field, which can attract or repel other materials. There are two main types of magnets: permanent magnets, which maintain a constant magnetic field, and temporary magnets, which only exhibit magnetic properties in the presence of an external magnetic field. Magnets typically have north and south poles, and opposite poles attract each other while like poles repel. They are commonly used in various applications, from electric motors and generators to magnetic storage media and medical equipment.
