Electromagnetic
Electromagnetic
Electromagnetic (pronunciation: /ɪˌlɛktrəʊmæɡˈnɛtɪk/) refers to the physical interaction that occurs between electrically charged particles. The term is derived from the Greek words "electron" meaning amber (from which the word electricity is derived) and "magnetis lithos" meaning magnesian stone, a type of iron ore.
Definition
Electromagnetic phenomena are defined in terms of the electromagnetic force, sometimes called the Lorentz force, which includes both electricity and magnetism as elements of one phenomenon.
History
The theory of electromagnetic was mainly developed by James Clerk Maxwell. The first known use of the term "electromagnetic" was in 1821 when Michael Faraday realized that electric current could create a magnetic field and was the first to associate the term with electricity.
