VSM Measurement System / Magnetic Measurement Instrumentation

WEISTRON Vibrating Sample Magnetometer (VSM)WEISTRON Vibrating Sample Magnetometer (VSM)

The WEISTRON Vibrating Sample Magnetometer (VSM) measures the magnetization of a sample of magnetic material under an external magnetic field by converting the dipole field of the sample into an ac electrical signal. The sample is driven to vibrate sinusoidally. The induced voltage in the pickup coil is proportional to the sample's magnetic moment. By measuring in an external magnetic field, we can obtain the hysteresis loops or magnetization curves of a material.
