Abstract
Abstract The functions of the two pairs of electrodes of a Hall generator are interchanged simultaneously with the reversal of the direction of polarization of the magnetic field acting on the Hall generator to reduce the inverse effect of the Hall generator during reversal of the direction of polarization of the magnetic field.
