A simple approach to coil design for vibrating sample magnetometers

Abstract

The recent paper by Bragg and Seehra (1976), although welcome for its rigorous approach to the problem of the theoretical EMF obtainable from pickup coils used in vibrating sample magnetometers, is incomplete since it does not pin-point the crucial factors governing coil pickup efficiency. In addition these authors make some statements which would be misleading to the uninitiated and thus require further comment. An attempt is made to clear up these shortcomings and demonstrate an extremely simple approach to coil design which follows directly from a little-quoted paper by Mallinson (1966).
