What is a Magnet?

A magnet is described as a material or object that produces a magnetic field. The most distinguishing feature of the magnet (because of its magnetic field) is its ability to create a force of attraction to attract or repel ferromagnetic materials or other magnets. A magnetic field surrounds a magnet and at any given point is specified by both direction and magnitude (or strength).

What is a Magnetic Field?

A magnetic field is described as the space around a magnet in which the effect of the magnet can be felt. The magnetic field is a force created by a permanent magnet, a force that is able to,

1. Pull other magnets and other ferromagnetic materials such as iron towards itself (attract)
2. Push other magnets away from itself (repel)

What is Electromagnet?

A magnet can be temporarily created by using a coil of insulated wire and electric current. This is called an electromagnet and lasts as long as the current is flowing. When a wire is wound around a magnetic core made from a ferromagnetic material like iron and an electric current is passed through the wire, a magnetic field is created which concentrates on the core. The magnetic field for this temporary magnet disappears when the current is switched off. The strength of this field can be controlled by controlling the amount of flow of electric current in the winding. The relative motion between a coil and a magnet results in a changing magnetic field which in-turn induces potential difference (thus current).

What is Electromagnetic Induction?

It is the phenomenon in which the potential difference (e.m.f.) is induced in the coil if there is a change in the magnetic flux linked with the coil.

What is Magnetic Flux?

The number of magnetic field lines passing through a fixed area is known as magnetic flux.
