In pheesics, specifically electromagnetism, the magnetic flux (eften denotit Φ or ΦB) through a surface is the component o the magnetic B field passin through that surface. The SI unit o magnetic flux is the weber (Wb) (in derived units: volt-seiconts), an the CGS unit is the maxwell. Magnetic flux is uisually measurt wi a fluxmeter, which contains measurin coils an electronics, that evaluates the chynge o voltage in the measurin coils tae calculate the magnetic flux.
