Answer:
Magnetic Flux (ϕ) represents the total number of magnetic lines of force in a magnetic field. Unit is Weber (wb).
The flux passing through the unit area through a plane at right angles to the plane is defined as magnetic flux intensity (B). Unit is Tesla (T) or (wb/m
If ϕ webers of magnetic flux is passing normaly through an area of A meter square
Or, ϕ is the dot product of B and A
=BA cos¢
