   Electromagnet
   An electromagnet is a solenoid with an iron core inserted into it. If a current flows in the coil, a magnetic field is generated. All the randomly oriented domains of the iron core then align in the presence of the field of the solenoid. Thus, the core greatly enhances the strength of the electromagnet

   electromagnet
   <physics> A mass, usually of soft iron, but sometimes of some other magnetic metal, as nickel or cobalt, rendered temporarily magnetic by being placed within a coil of wire through which a current of electricity is passing. The metal is generally in the form of a bar, either straight, or bent into the shape of a horseshoe. ... Source: Websters ...

   Electromagnet
   An `electromagnet` is a type of magnet in which the magnetic field is produced by the flow of an electric current. The magnetic field disappears when the current ceases.

    electromagnet
    A magnet constructed from a soft iron core around which is wound a coil of insulated wire. A magnetic field is set up when an electric current is passed through the wire, and it disappears when the current is switched off. This creates a magnet that can be turned on and off.

    electromagnet
    electromagnet, device in which magnetism is produced by an electric current. Any electric current produces a magnetic field, but the field near an ordinary straight conductor is rarely strong enough to be of practical use. A strong field can be produced if an insulated wire is wrapped around a soft ...
