    en.wikipedia.org/wiki/Magnetic_switch

    Magnetic switch. Magnetic switch is an electrical switch that makes or breaks contact in the presence of a magnetic field.Applications include situations where it is not desirable or possible for moving elements to make direct contact with the switch, such as in explosive environments, submerged in liquids, and where repetitive contact with a mechanical switch would result in undesired wear.

    en.wikipedia.org/wiki/Magnetic_starter

    Contactor with overload relay. A magnetic starter is an electromagnetically operated switch which provides a safe method for starting an electric motor with a large load. Magnetic starters also provide under-voltage and overload protection and an automatic cutoff in the event of a power failure.

  4. Magnetic switchable device - Wikipedia

    en.wikipedia.org/wiki/Magnetic_switchable_device

    A magnetic switchable device (often called a magnetic base) is a magnetic fixture that uses one or more permanent magnets in a configuration that allows the external field to be turned on or off. They are used in many applications including optics, metalworking, lifting, and robotics, to attach items to metal surfaces in a secure but temporary way.

  5. Transcranial magnetic stimulation - Wikipedia

    en.wikipedia.org/wiki/Transcranial_magnetic...

    Transcranial magnetic stimulation ( TMS) is a noninvasive form of brain stimulation in which a changing magnetic field is used to induce an electric current at a specific area of the brain through electromagnetic induction. An electric pulse generator, or stimulator, is connected to a magnetic coil connected to the scalp.
