Magnetism Magnetism refers to the physical phenomena arising from the forces caused by magnets and objects that produce fields to attract or repel other objects. It broadly categorized as, 1)Magnets 2)Magnetization 3)electromagnets

Magnets A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field.

Magnetization Magnetization: A process of converting nonmagnetic material into magnetic material is termed as magnetization. Demagnetization: A process of removing the magnetic field from an object, example: magnetic bar is called demagnetization.

Electromagnets An Electromagnets is a type of magnet in which the magnetic field is produced by an electric current. The strength of the electromagnet can be improved .

Magnetic Field around a solenoid When an electric current flows through a solenoid, a magnetic field is produced inside and outside the coil.
