Electromagnet
Electromagnet (/ɪˈlɛktrəʊˌmæɡnɪt/) is a type of magnet in which the magnetic field is produced by an electric current. The magnetic field disappears when the current is turned off.
Etymology
The term "electromagnet" is derived from the Greek words "electron" meaning amber (from which the word electricity is derived) and "magnet" which is named after Magnesia, a region in Thessaly where magnetic iron ore was found.
