%X The measurement of the magnetic susceptibility of rock specimens, at low fields, commonly employs instruments which measure the change in an inductive circuit when a sample is introduced into the magnetic flux path of the inductor. In many cases this takes the form of a transformer bridge. Some time ago the CSIRO Division of Mineral Physics recognised a need for such a bridge for use in research. Known existing designs appeared inadequate, and it was considered expedient to develop a new instrument with significantly improved performance.
