also electro-magnet, "magnet which owes its magnetic properties to electric current," 1822; see electro- + magnet.

A magnetic field produced when an electric current is passed through a wire wrapped around a piece of iron.

material or object whose magnetic field is produced by electricity.

Magnet constructed from a soft iron core around which is wound a coil of wire. A magnetic field is generated when an electric current is passed through the wire.

A magnet consisting of a solenoid with an iron core, which has a magnetic field only during the time of current flow through the solenoid. Learn more in our Electromagnets article.

An electromagnet is a type of magnet whose magnetic field is produced by the flow of electric current. The magnetic field disappears when the current ceases.

magnet consisting of a coil of wire wrapped around a core that becomes strongly magnetized when            current flows through the coil producing a magnetic field.  electromagnetic radiation - [..]

A coil that acts like a magnet only when electricity is applied. When electricity is removed, the magnetism stops. Most often used as a solenoid, but sometimes used under the playfield to affect ball [..]

A magnet formed by a solenoid that can be turned on and off by turning the current on and off

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 p [..]

(n) a temporary magnet made by coiling wire around an iron core; when current flows in the coil the iron becomes a magnet

A very strong temporary magnet that can be turned on and off (Lesson 24)

A device made of wire coils that produces a magnetic field when electricity flows through the coils.

A coil of wire that is wrapped around a soft iron core that is magnetized when electric current flows through it.

core of magnetic material, generally soft iron, surrounded by a coil of wire through which electrical current is passed to magnetize the core.

— a temporary magnet formed when electric current flows through a wire or other conductor.

a temporary magnet consisting of a set of coils wound on an iron core. The device becomes magnetic when electricity is passed through the coils.

alternator an alternator which uses electromagnet to produce a magnetic field.

a magnet which produces a magnetic field by passing electrical current through a coil wire wrapped around a soft iron core.

    A device that produces a magnetic field as the result of current flow through a coil of wire.

A magnet made of a current-carrying solenoid wrapped around an iron core.

A temporary magnet made of a ferromagnetic core wound with insulated wire through which is passed an electric current. The current flow through the windings causes a magnetic field to build that will attract magnetic material.

a coil that has a soft iron core and that acts as a magnet when an electric current is in the coil

An electrically excited magnet capable of exerting mechanical force or of performing mechanical work. A part that is magnetized only when subjected to an electric current.
