“…It can also act as a sensor by utilizing the motional electromotive force generated from the motion of a coil in the magnetic field [4]. Application examples of the electromagnetic transducer include but are not limited to position control [5,6], sound amplification using loudspeakers [7,8,9,10,11], vibration isolation [12], valve actuation [13], load support magnetic bearings [14], magnetic levitation [15], vehicle suspension [16,17,18], and energy harvesting [19,20,21].…”
