Magnetic Flux

Magnetic Flux

Magnetic Flux or Magnetic Induction, denoted by B, is a measure of the strength of a magnetic field over a given area, and is expressed in Weber.

Magnetic Induction
Magnetic Flux (Wikipedia)

In physics, specifically electromagnetism, the magnetic flux through a surface is the surface integral of the normal component of the magnetic field B over that surface. It is usually denoted Φ or ΦB. The SI unit of magnetic flux is the weber (Wb; in derived units, volt–seconds), and the CGS unit is the maxwell. Magnetic flux is usually measured with a fluxmeter, which contains measuring coils, and it calculates the magnetic flux from the change of voltage on the coils.
