In the device, a movable yoke for continuously changing the distance between opposing surfaces of the yoke is disposed on at least one of the pair of yokes, and a magnetic path formed by the permanent magnet, the yoke, and the movable yoke is arranged. A magnetic field emitting device characterized in that the magnetic resistance of the magnetic field is continuously variable.
