Magnetic flux

Magnetic flux, is a measure of quantity of magnetism, taking account of the strength and the extent of a magnetic field.The flux through an element of area perpendicular to the direction of magnetic field is given by the product of the magnetic field density and the area element. More generally, magnetic flux is defined by a scalar product of the magnetic field density and the area element vector.
