Magnetic Flux: Lines, Units, Force and Density!

What is Magnetic Flux?

Definition: Total number of magnetic lines of force passing through the given surface in a magnetic field is called as Magnetic Flux.

Unit of Magnetic Flux:

The unit of magnetic flux in SI system of units is weber (Wb). And in CGS system, its unit is 'maxwell'.

1 weber ≈ 10⁸ maxwell

One weber of magnetic flux is defined as the flux (number of lines) radiated out by a unit North pole of a mgnet.

What is Magnetic Flux Density?

It is defined as the flux per unit area, measured in a plane perpendicular to the flux. Unit of Magnetic Flux Density is Tesla (T) and it is denoted by B.

Magnetic Flux basics:

• It is used for representing the magnetic field of a magnet. These lines are imaginary and they do not have any physical existence.
• Magnetic Flux was introduced by the very much famous scientist Michael Faraday. He used it to give a pictorial representation of the distribution of the magnetic field of a magnet. Magnetic Flux is also know as Magnetic Lines of Force.
