Magnetic Flux

The surface integral of the product of the permeability of the medium and the magnetic field intensity normal to the surface. The SI Unit of magnetic flux is the weber. An electromotive force of 1 volt is induced in a circuit through which the magnetic flux is changing at a rate of 1 weber per second.

The magnetic field is established around an energized conductor or permanent magnet. The field is represented by flux lines creating a flux pattern between opposite poles. The density of the flux (magnetic flux density) lines is a measure of the strength of the magnetic field.
