MAGNETIZATION OF MASS STANDARDS AS DETERMINED BY GAUSSMETERS, MAGNETOMETERS AND SUSCEPTOMETERS

摘要

Magnetization of a mass standard can lead to weighing errors. This is because most modern balances are sources of non-uniform magnetic induction. Although the problem of unwanted magnetic forces is well known, the characterization of the magnetic properties of mass standards and balances can be problematic. This paper compares the kind of information that can be obtained from three types of instruments: Hall-probe gaussmeter, fluxgate magnetometer and susceptometer.
