Claim 11:
12. The transducer of claim 11, wherein the transducer is a magnetic-potential transducer, and the transducer further comprises:
at least one alternating magnetic field generating device configured to generate an alternating magnetic field, the alternating magnetic field is orthogonal or partially orthogonal to the static magnetic field; and
at least one movable device provided with a magnetic conductive material, at least a part of the magnetic conductive material is arranged in an area where the alternating magnetic field overlaps with the static magnetic field, so that the static magnetic field and the alternating magnetic field are converged,
wherein a magnetic field force generated by an interaction between the static magnetic field and the alternating magnetic field is applied to the magnetic conductive material so as to drive the movable member to move.
