What is Magnetic Induction?

Magnetic induction is the fundamental character of a magnetic field at a point. It is a procedure by which a substance, like, iron or steel, becomes magnetized by a magnetic field.

Magnetic induction at a point in a magnetic field is the force experienced by the unit north pole placed at that point. It is denoted by B. Its unit is N/Am.

It is a vector quantity. It is also called a magnetic flux density.

If a magnetic pole of strength m placed at a point in a magnetic field experiences a force F, the magnetic induction at that point is: B = F/m
