Electromagnets

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current.

• Electromagnets usually consist of wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole, denoting the centre of the coil.

Properties of Electromagnets:-

• Attractive Property – Ferromagnetic materials like iron, nickel and cobalt are attracted by magnets

• Repulsive Property – Like poles repel each other while unlike poles attract each other.

• Directive Property – A freely suspended magnet always points in the north-south direction.

Uses of Electromagnets

1. Generators, motors, and transformers
2. Electric buzzers and bells
3. Headphones and loudspeakers
4. Relays and valves
5. Data storage devices like VCRs, tape recorders, hard discs, etc.
6. Induction cooker
7. Magnetic locks
8. MRI machines
9. Particle accelerators
10. Mass spectrometers
