How do eletric magnets work
WebAll electromagnets work on the principle that an electric current in a wire produces a magnetic field. In fact it is remarkably straightforward to make an electromagnet. Simply … WebJun 14, 2016 · In Maglev, superconducting magnets suspend a train car above a U-shaped concrete guideway. Like ordinary magnets, these magnets repel one another when matching poles face each other. “A Maglev train car is just a box with magnets on the four corners,” says Jesse Powell, the son of the Maglev inventor, who now works with his father.

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 concentrate… WebAll electromagnets work on the principle that an electric current in a wire produces a magnetic field.
