certain speed. The coil at one end of the waveguide acts as the receiver while the other end connects to the damper. The damper attenuates the torsional wave to avoid reflecting it back and corrupting at the other end. When the torsional wave passes under the receiving coil, the flux lines of the residual magnetic field change [11-15].
