Permanent magnets are materials that maintain a persistent magnetic field without the need for an external power source, due to the alignment of their atomic magnetic moments. They are essential in various applications, from simple refrigerator magnets to complex technologies like electric motors and data storage devices.

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. It is generated by electric currents and magnetic dipoles, and is characterized by both a direction and a magnitude, which can be visualized through field lines that extend from the north to the south pole of a magnet.
