Magnetic Flux
Flux is defined as the penetration of magnetic field through a given area.
Flux = Area x Magnetic Field
If the magnetic field penetrates the given area at an angle (not perpendicular, since cos90 = 0)
Flux = A x B cos a
where A is the area, B is the magnetic flux and a is the angle of penetration.
A flux passing through a coil of N turns of wire is said to have a link with the coil. Therefore
Magnetic Flux Linkage is given by:
Flux Linkage = Number of coil turn x Magnetic Flux
