Magneto-optical glass is an important part of the optical current sensor. The use of MR3-2 magneto-optic glass as a magneto-optical medium for optical current sensors to study their response characteristics will promote the development of optical current sensors. The Faraday magneto-optic effect experiment platform was used to study the response of the sensor under AC sinusoidal excitation. Response characteristics include: response waveform, amplitude characteristics, frequency characteristics and temperature characteristics. The experimental results show that the optical current sensor based on this new type of magneto-optical medium has excellent response waveform and amplitude characteristics, but its frequency characteristic is not ideal. In different temperature range, the response amplitude with the rate of change of temperature is basically the same.
