Magnetic induction sensor principle

The principle of magnetic sensors principle of magnetic Position Sensor magnetic field lines through the path of the permanent magnet N pole of a stator and a rotor air gap between the rotor lobes and the stator-rotor lobes a head gap between the magnetic head a magnetic board First S pole of the permanent magnet. When the signal rotor rotates, the air gap of the magnetic circuit will be changed periodically, through the magnetic circuit and the magnetic flux along the magnetic Camshaft Position Sensor coil changes periodically. According to the principle of electromagnetic induction, inductive sensing coil will produce alternating electromotive force. Since the rotor lobe air gap between the magnetic head magnetic circuit and directly affect the output voltage level of the sensing coil, due to
