Flux Meter





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)
