Abstract
A Lorentzian force type fibre-optic magnetic sensor is reported attaining frequency-independent sensitivity in the range 1 Hz to 10 kHz with minimum detectable field down to 50 nT. It is also shown that this technique can introduce frequency superimposition, which enables measurement of AC magnetic fields at different points simultaneously with one interferometer
