Abstract

This paper describes an experimental study of the shielding of 60 Hz magnetic fields with nested long cylinders with open ends and short cylinders with capped ends, constructed from multiple layers of steel and aluminum. Measurements of shielding factor were made for a large number of specific configurations of steel and aluminum in shields of up to eight layers, with both externally applied uniform fields and enclosed dipole sources. Measured results are compared with calculated results from a recently developed computational tool for multilayered shielding, with generally excellent agreement
