Some Uses of the Torque Magnetometer

Abstract

The history of torque measurement as an index of ferromagnetic anisotropy is outlined. A simple magnetometer for torque measurement is described in detail and uses for the instrument are discussed. These include the measurement of anisotropy constants, coercive force, complete magnetization curves for single directions, and rotational hysteresis losses. With auxiliary ballistic measurement residual inductions and demagnetizing factors are obtainable.
