A Level Physics ELECTROMAGNETISM Magnetic flux.

MAGNETIC FLUX
Magnetic flux is a measure of the number of fields lines passing through an area. It is equal to the product of the area ,A, and the flux density there ,B, times the cosine of the angle ,O, between the normal to the area and the field lines.

Q = A B Cos( O )
where Q is the magnetic flux. Magnetic flux is measured in Webers ( W).
