Electromagnetism (article) Khan Academy

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole in the center of the coil. The magnetic field disappears when the current is turned off. The wire turns are often wound around a magnetic core made from a ferromagnetic or ferrimagnetic material such as iron; the magnetic core concentrates … WebFor working of electromagnetic clutch, it essentially requires four parts. They are Engine Flywheel, winding, Clutch Plate and Pressure plate. The explanation of all the parts is as follows. The engine flywheel is represented with A and the winding B is incorporated in the flywheel. The winding B is supplied with current from the dynamo of battery. continuation budget
