4 Overview

Alternating magnetometer for measuring an alternating magnetic field magnetic induction value. Depending on the working principle of the alternating magnetic VSM main electromagnetic induction magnetometer and alternating Hall magnetometer. 4.1 Electromagnetic induction magnetometer When the magnetic flux passing through the conductor loop changes induced electromotive force is generated in the loop, a phenomenon known as electrical Magnetic induction effect. According to the law of electromagnetic induction, when the coil is placed in a sinusoidal alternating magnetic field, having the formula (1) according to the relationship. B = ESW 2πfScosθ (1) Where. B --- alternating magnetic field magnetic induction, T; ESW --- induced electromotive force generated in the coil, V; f --- frequency of the alternating magnetic field, Hz; S --- coil turns area, m2; And the angle θ --- alternating magnetic field coil magnetic axis, (°). Magnetometer principle of electromagnetic induction made a count called electromagnetic induction magnetometer. 4.2 Hall magnetometer When an external magnetic field is applied perpendicular to the current semiconductor film, a semiconductor film in perpendicular to the magnetic field and current party To generate an electromotive force, a phenomenon known as the Hall effect. According to Hall effect, when the Hall element is placed in an alternating magnetic field, having the formula (2) the relationship. ......
