    Manufacturing Processes for Permanent Magnets: Part I

    A permanent magnet is unique in that once produced, it provides a magnetic flux with no energy input, hence zero operating cost. By contrast, electromagnets require a continuous electrical current to generate a magnetic field and operate. Permanent magnets today are used in a wide range of motors, wind turbines, electronics, and medical devices.

    10 Examples Of Permanent Magnets

    The major difference between an electromagnet and permanent magnet is that the former can have a magnetic field when electric current flows through it and disappears when the flow of the current stops. On the other hand, permanent magnets are made up of magnetic material that is magnetized and has its own magnetic field.
