Further Development of the Vibrating-Coil Magnetometer

Abstract
The vibrating‐coil magnetometer is a versatile and sensitive instrument, with greater freedom of sample environment than can otherwise be obtained. There are several practical factors which tend to degrade the performance of the instrument below theoretical expectations. These difficulties are discussed, and improved techniques for overcoming them are described. The resulting performance is compared both to that of the original instrument and to that theoretically obtainable. The present performance is shown to be within an order of magnitude of the theoretical limitation, which constitutes a marked improvement in the quality of the vibrating‐coil magnetometer. The capabilities of the instrument are illustrated by several experiments.
