Permeable Prolate Spheroid in an External Field: Demagnetization and Gradiometer Performance

Abstract

A permeable prolate spheroid is used as a model for the core of a search coil gradiometer. The performance of the gradiometer is determined by flux concentration and demagnetization due to the core geometry, just as in the case of a search coil magnetometer. Performance curves are given for both magnetometer and gradiometer.
