# 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 Flux (Wikipedia)

In physics, specifically electromagnetism, the magnetic flux (often denoted Φ or ΦB) through a surface is the surface integral of the normal component of the magnetic field B passing through that surface. The SI unit of magnetic flux is the weber (Wb) (in derived units: volt ${\displaystyle \cdot }$ seconds), and the CGS unit is the maxwell. Magnetic flux is usually measured with a fluxmeter, which contains measuring coils and electronics, that evaluates the change of voltage in the measuring coils to calculate the measurement of magnetic flux.
