ABSTRACT:
The flux densities formed by plural electromagnet poles M1to M12which are arranged at a predetermined interval in a circumferential direction of a rotary body1at the same position in an axial direction of the rotary body1are gradually changed in the circumferential direction of the rotary body. Even if there is a difference between the maximum value of the flux density and the minimum value, the change of the flux densities between the adjacent electromagnet poles is small and smooth. Accordingly satisfactory detective sensitivity and detection results can be obtained.
