magnet produced by placing a coil of wire around a steel or iron bar. When current flows through the coil, the bar becomes magnetized and will remain so as long as the current continues to flow.
A coil of wire, usually wound on an iron core, which produces a strong magnet field when current is sent through the coil.
A magnet of a soft-iron core wound with a current-carrying coil of insulated wire. The current produces the magnetization of the core.
(MRI) A magnet which is magnetized by a current-carrying coil round it. These can produce much larger magnetic field than permanent magnets.

An electrical device that produces a magnetic field.
magnet created by coiling current-carrying wire, thereby polarizing the induced magnetic field.
a type of magnet that utilizes coils of wire, typically wound on an iron core, so that as current flows through the coil it becomes magnetized. See also Resistive Magnet, Superconducting Magnet.
a temporary magnet made by coiling wire around an iron core; when current flows in the coil the iron becomes a magnet

a type of magnet in which the magnetic field is induced by a flow of an electric current through a coil of wire
A magnet made by wrapping a coil of wire around an iron bar and passing an electric current through the coil. Electricity and magnetism
A magnet formed by a coil of wire with an electrical current running through it.
material magnetised by the use of electricity.
An electromagnet is formed by passing a current through a coil of wire. Unlike normal magnets, electromagnets can be turned on and off. Electromagnets
A magnet consisting of wire wound around a soft iron core. It becomes an active magnet when current is passed through the wire, and it ceases to be a magnet when the current stops. See: Magnet
A coil of wire that develops a concentrated magnetic field likened to that of a N-, S-Pole magnet when an electric current flows through the coil. Note that a magnetic field exists, unconcentrated, about a straight wire carrying current.
A magnetic field produced when an electric current is passed through a wire wrapped around a piece of iron.
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.
is a magnet, consisting of solenoid with an iron core, which has a magnetic field existing only during the time of current flow through the coil.
A coil of wire wound about a magnetic material, such as iron, that produces a magnetic field when current flows through the wire.
A device consisting of a ferromagnetic core and a coil that produces appreciable magnetic effects only when an electric current exists in the coil.
A magnet created from wire coils that produces a magnetic field when electricity flows through the coils
A device that uses an electric current to produce a concentrated magnetic field. Any coil with current flowing through it is an electromagnet. All current, however, produces some sort of magnetic field.
a wire coil around a metal core (usually iron) that acts like a magnet when an electric current flows through it
A coil of wire wrapped an iron core. When electric current flows through wire, the assembly becomes a magnet.
A magnet, the properties of which are exhibited under and dependent upon, the engergizing influence of an electric current.
A device that produces a magnetic field when an electric current is applied.
A coil of wire that is wrapped around a soft iron core that is magnetized when electric current flows through it.
A piece of soft iron surrounded by a coil of wire, through which a current of electricity may be passed, rendering the iron temporarily magnetic.
An electrically excited magnet capable of exerting mechanical force or of performing mechanical work.
Wrapping a wire into a coil creates an electromagnet, which behaves just like a regular permanent bar magnet when the current is flowing. (Basic Science/Electricity/electromagnetism.htm)(Course Material/MagParticle/Equipment/equipment1.htm)
Mechanism, which is made of, a magnetic material wrapped with an electrically conductive coil through which the current is passed to bring about magnetism in the material.
A magnet with a coil of wire that has a current passing through it. The magnetic field can be made stronger by coiling the wire around an iron core.
A coil of wire usually wound on a soft iron or steel core. When current is passed through the coil a magnetic field is generated. The core provides an easy path for the magnetic lines of force. This concentrates the field in the core.
An electromagnet is a type of magnet in which the magnetic field is produced by a flow of electric current. The magnetic field disappears when the current ceases.
