The comparison between OCT(Optical Current Transducer) and traditional electromagnetic current transformer shows that the former is the ideal substitute for the latter with its good performance.
An electromagnetic acoustic transducer (EMAT) can produce and receive ultrasonic waves though electromagnetic coupling.
