Flux is the presence of a force field in a specified physical medium, or the flow of energy through a surface. In electronics, the term applies to any electrostatic field and any magnetic field.
Magnetic flux is the number of magnetic field lines passing through a surface placed in a magnetic field. We show magnetic flux with the Greek letter; Ñ. We find it with following formula; Ñ=B.A.cosÓ¨. Where Ñ is the magnetic flux and unit of Ñ is Weber (Wb) B is the magnetic field and unit of B is Tesla. A is the area of the surface and unit of A is m2. Following pictures show the two different angle situation of magnetic flux.
