摘要： A sensor for identifying a surface of a magnetic body (11) having an uneven surface, the sensor comprising a detecting magnetic pole portion (12) for detecting the magnetic body, the detecting pole portion (12) and the magnetic body (11) being movable relative to each other and a reference magnetic pole portion (13) across from a reference surface that is different from the uneven surface, wherein the distance between the reference portion (13) and the reference surface is maintained substantially constant. Wound round the detecting pole portion (12) and the reference pole portion (13) are magnetising coils (14) for generating magnetic fluxes. Wound round the detecting pole portion (12) and the reference pole portion (13) are detecting coils (15 and 16) for detecting the magnetic fluxes generated in the magnetising coils. The arrangement being such that when there is relative movement between the detecting portion (12) and the magnetic body (11), the uneven shape of the magnetic body (11) causes the distance between the detecting portion (12) and the magnetic body (11) to change and the uneven shape is identified based on the output from the detecting coils (15 and 16).
