magnetic flux

American  

noun

Electricity.

1. the total magnetic induction crossing a surface, equal to the integral of the component of magnetic induction perpendicular to the surface over the surface: usually measured in webers or maxwells.

magnetic flux British  

noun

1.  φ.  a measure of the strength of a magnetic field over a given area perpendicular to it, equal to the product of the area and the magnetic flux density through it

magnetic flux Scientific  

1. The lines of force associated with a magnetic field. The strength of magnetic flux is equivalent to its magnetic flux density per unit area. The SI unit of magnetic flux is the weber.

2. See magnetic flux density
