Principle of Fluxmeters
As magnetic flux cuts through the search coil, it induces a
voltage in the search coil. As per Faradays law of induction,
this
voltage is the differential of the magnetic flux that passed through
the search coil. By feeding this voltage into an integrating
fluxmeter,
the integration process removes the differential (of the search coil)
resulting in the fluxmeter displaying the total magnetic flux.
Fluxmeters require a dynamic component for the measurement, as it is
necessary for magnetic flux to cut the search coil to produce a
voltage.
By calibrating the fluxmeter with the area and number turns of
the search coil it is possible to display values of flux density on a
fluxmeter (Tesla, gauss) as well as magnetic flux (Webers, Vs or
Maxwell
turns)
