Etymology
From electro- (combining form relating to electricity, from Greek elektron "amber") + magnetic (from Greek magnetikos, from Magnesia, a region in ancient Greece where magnetic iron ore was found). First used in the early 19th century following Hans Christian Oersted's discovery of the relationship between electricity and magnetism in 1820.
