Abstract
In the present invention, a detection coil and a cancellation coil are closely provided and electrically connected in series to cancel induction noise. The cancellation coil may be disposed at a position not to sense the rotation. An axis of the cancellation coil may be provided in parallel to an axis of the detection coil. The numbers of turns for the cancellation coil may be the same as those for the detection coils. The cancellation coil may be disposed coaxial to the detection coils.
