要約(英語): In recent years, there are many instruments using time varying magnetic fields up to 100 kHz, for example IH cooker, wireless power transfer systems, and so on. Therefore, it is required to construct the magnetic field (MF) probe with the ability to measure wide band frequency range for evaluating emitted MF from such instruments. The characteristic of MF distributions from these instruments is highly localized in the vicinity of equipments. A prototype of the magneto-optical probe applying the Faraday Effect has been developed to measure and evaluate environmental magnetic fields from the low frequency to the intermediate frequency range. This probe is fabricated with single Faraday rotator by incorporating optical elements, i.e. a polarizer and an analyzer to avoid the fluctuation of measurement value caused by movement of optical fiber cables. Consequently, stable output signal from the developed probe is observed whenever the probe head and optical fibers are moved under applying the sinusoidal magnetic fields with the frequency of up to 500 Hz.
