Measurement technology of magnetic flux and its application

The measurement technology of magnetic flux is used for measuring magnetic field intensity of surroundings. Under the action of magnetic excitation, the induction coils around the high-permeability and low-coercive force soft magnetic material have the even harmonic electric potential, the even harmonic electric potential changes with the magnetic field intensity of surroundings and can be measured by using the high-performance filter. The typical application of the measurement technology of magnetic flux is to measure the orientation of body, it is very important to correct the error of the structure parameter in the practical application.
