Abstract
A magnetic sensing systemaccording to the present invention is provided with a sensing devicethat generates an electrical signal according to the strength of a magnetic field that changes in response to the action of an external force, and a detection devicethat detects a physical quantity associated with the action of the external force from a change in the magnetic field based on the electrical signal from the sensing device. The sensing deviceincludes magnetic field generation meansandthat generate a desired measurement magnetic field of different strengths from a site that is displaced by the action of the external force, and a magnetic field measurement meansthat measures the strength of a surrounding magnetic field including the measurement magnetic field. The detection deviceuses a relational expression stored in advance to specify, on the basis of fluctuations over time in the measurement magnetic field of different strengths, a magnetic interference amount corresponding to the strength of an interference magnetic field generated separately from the measurement magnetic field, and calculates the physical quantity by removing the influence of the magnetic interference amount.
