Since it is common knowledge that every substance has certain magnetic properties present within them henceit is important to note down the area and field of its action. When a number of magnetic field lines pass through a specific surface, that amount of lines is known as magnetic flux.
Magnetic flux’s S.I. Unit is Weber, and it helps in linking a single coil and to reduce this flux to zero, its e.m.fis taken as one volt. At uniform rate, this is reduced to zero at certain cases. It is denoted by ɸ.
Magnetic Flux Density:
Denoted by B, this is the total amount of magnetic flux that is present in a particular area and placed against direction of magnetic flux in a perpendicular manner. Also known as magnetic induction, this is represented by Wb/m2. It is also known as Tesla.
