Electromagnets are found in things like doorbells,telepones,radios, VCR's,DVD players,computers/laptops,tape decsk,generators,and sound speakers.
I don't see why not. It would have to be electromagets providing the magnetic field, and they would draw electricity from a generator that is powered by the motor. For electric cars, however, the brakes would draw too much power and drain the battery.
Both permanent magnets and electromagnets can be used on doors. Permanent magnets are used in simple applications like cabinet doors, while electromagnets are commonly used in commercial settings for security doors or in access control systems. Electromagnets can be activated and deactivated as needed, providing greater control over door access.
Maglev stands for Magnetic Levitation (primarily used in trains) it refers to how they use the repulsion of electromagets to "fly" from 1cm - 10cm above an electromagnetic track (guideway) the applications are mainly for highspeed transport because as there is no friction, these trains have a record speed of 518km/h (311mph).
