CHARACTERIZATION OF THE MAGNETIC FIELD OF A WEIGHING INSTRUMENT

M. Gläser, M. Mecke

Abstract

A mathematical model of the magnetic interaction between a weighing instrument and a weight and measurements of the distribution of the magnetic field in the space above a top loading weighing instrument are presented. Four parameters have been evaluated that characterize sufficiently well the magnetic property of the instrument, provided the weight's magnetic susceptibility and magnetization are homogeneously distributed over its volume. The magnetic field of the weighing instrument is modelled by a magnetic dipole field. The integration over the weight's volume was made by stepwise numerical subdivision of the volume into subvolumes.
