Abstract
The principles of operation of a modulated inductance magnetometer and the problems that have been encountered in an attempt to realize the expected sensitivity are discussed. A magnetometer for which inductance modulation is effected by a superconducting plane vibrating near a long inductance element is described. The suitability of this magnetometer to the measurement of small magnetic fields is considered in conjunction with the most recent experimental results.
