Abstract
An apparatus used at the Geological Survey of Canada for magnetic cleaning purposes is described. With this apparatus viscous components of remanent magnetization were effectively removed from a group of uniformly magnetized specimens although an appreciable scattering in magnetization directions was observed after treatment at high peak field intensity. Tests were conducted to verify that the scattering was not inherent in the design of the apparatus.
