Magnetic Flux Formula - Softschools

Magnetic flux is the product of the average magnetic field times the perpendicular area that it crosses. Magnetic flux = Magnetic field * Area * (angle between the planar area and the magnetic flux) The equation is: Φ = B A cos(θ) Where: Φ: Magnetic Flux. A: Area. B: Magnetic field

Likewise, if the magnetic flux is decreased then the induced emf will oppose this decrease by generating and induced magnetic flux that adds to the original flux. Lenz's law is one of the basic laws in electromagnetic induction for determining the direction of flow of induced currents and is related to the law of conservation of energy.

Magnetic flux - Wikipedia

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 electronics, that evaluates the change of voltage in the measuring coils to calculate the measurement of magnetic flux.
