Abstract

A procedure developed for the calibration of a magnetic sensor in spatially strongly inhomogeneous magnetic field is presented in this paper. Assuming that the sensor is linear and it does not significantly disturb the magnetic field to be measured, its output signal is approximated as the weighted sum of the field values calculated theoretically around the sensor. The weighting coefficients are obtained by finding the best fit of the actual experimental output and the theoretical prediction of the measured field in the least square sense. Using the presented procedure, sensors can be calibrated for the measurement of spatially strongly inhomogeneous magnetic fields, consequently such sensors can be applied to get the field distribution map of inhomogeneous fields.
