Magnetic Flux

by amsh

The Magnetic flux Φ through any surface held in a magnetic field b is measured by the total number of magnetic lines of force crossing the surface

 

where d S = small area element through which line is passing.

Units

The S.I. unit of magnetic flux is weber (Wb). One weber is the amount of magnetic flux crossing over an area of 1 metre2 held normal to a uniform magnetic field of one tesla.

Thus                           1 weber = 1 tesla x 1 m2

The c.g.s. unit of Φ is maxwell (Mx),

where             1 weber = 108 maxwell
