We present a novel scheme for compensation of transmission loss variations in Faraday effect-based fibre optic magnetic field sensors. Light is sent through the sensing element in opposite directions to form the two signal channels needed for the compensation. Experiments have been made with a time-multiplexed multimode system in which IR emitting diodes are alternately used as emitters and detectors. With transmission loss variations of less than 25%, which is reasonable in a real system, the resulting error is well below 1%.
