[ih-lek-troh-mag-nit] /ɪˌlɛk troʊˈmæg nɪt/
a device consisting of an iron or steel core that is magnetized by electric current in a coil that surrounds it.
a magnet consisting of an iron or steel core wound with a coil of wire, through which a current is passed
1831; see electro- + magnet.
A device consisting of a coil of insulated wire wrapped around an iron core that becomes magnetized when an electric current flows through the wire. Electromagnets are used to convert electrical control signals into mechanical movements. See Note at magnetism.
A magnet created by passing an electric current through coils of wire. Electromagnets are widely used in common electrical systems.

- Electromagnetic compatibility
hardware, testing (EMC) The extent to which a piece of hardware will tolerate electrical interference from other equipment, and will interfere with other equipment. There are strict legal EMC requirements for the sale of any electrical or electronic hardware in most countries, although the actual standards differ. See, for example, EMCNet (http://emcnet.com/).
