Torque Magnetometry in DC Fields

A torque magnetometer is one of the most sensitive magnetic property measurement devices.

It basically measures a magnetic torque (not direct magnetization) in a very short time period – short enough to be used even in a pulsed magnet. Currently two versions of the torque magnetometer are available: the capacitive torque magnetometer and piezo-resistive torque magnetometer.
