摘要： PROBLEM TO BE SOLVED: To provide a magnetic position detecting apparatus which is good for being made compact and low-power-consumption, and can precisely detect a position and a movement value of a moving object.
SOLUTION: A magnetoelectric device 104 is disposed near one end 112a of a magnetized area 112 of a magnetic drum 111, so as to be opposite and close to it in a noncontact fashion. Therefore, a change in a strength of a magnetic field being applied to the magnetoelectric device along with a rotation of the magnetic drum, is represented by a sine wave on which a DC bias magnetic field is superimposed. The influence of the hysteresis characteristic of a magnetic sensor on an output signal wave of the magnetic position detecting apparatus can be reduced by using the DC bias magnetic field.
