Answer 2

An electromagnet is one which behaves as a magnet when current is allowed to flow through it.

• The structure of an electromagnet consists of a wire coiled around a ferromagnetic substance (generally an iron core).
• When current is allowed to flow through the electromagnet, a magnetic field is created.
• The magnetic flux is concentrated in the region of core.
• Electromagnets have a widespread application, for instance in motors, solenoids, loudspeakers, hard disk, etc
