Final report (draft B) on EUROMET Project No. 446: International comparison of magnetic flux density by means of field coil transfer standards

Abstract

Within the EUROMET Project No. 446 participants from eight European countries have measured the magnetic flux density with frequencies up to 20 kHz generated in a field coil acting as transfer standard. Different methods have been applied by the various institutes to determine the coil constant of the standard and its frequency dependence in ac and dc fields.
