Etymology

Origin of electromagnetic

First recorded in 1815–25; electro- + magnetic

Explanation

The adjective electromagnetic describes a powerful natural force that's caused by an electrical charge. Objects that have an electromagnetic charge act like ordinary magnets, attracting and repelling other objects — but the source of their magnetism is an electric current flowing inside them. Electromagnetic, a combination of electric and magnetic, dates from the 1820s, soon after the force itself was discovered by a Danish scientist who noticed a magnetic compass needle moving when it was close to a live electric wire.
