Its use to measure magnetization is based on the Faraday’s laws of electromagnetic induction. The induced voltage in the pickup coil is proportional to the sample's magnetic moment, but does not depend on the strength of the applied magnetic field. In the process, a sample is placed inside a uniform magnetic field to magnetize the sample. A vibrating sample magnetometer (VSM) is a laboratory instrument for measuring the magnetic properties of a material.

Wu, “First-order- Vibrating-sample magnetometry (VSM) is a scientific tool that measures magnetic properties. Commercial systems use linear actuators of some form. In a VSM, a sample is placed within suitably placed sensing coils, and is made to undergo sinusoidal motion, i.e., mechanically vibrated. Instrum. Historically, these systems were developed using modified audio speakers, though this approach was dropped due to the interference through the produced in-phase magnetic noise, as the magnetic flux through a nearby pickup coil varies sinusoidally. The sample dipole moment is made to undergo a periodic sinusoidal motion at a fixed frequency using a transducer drive head to vibrate a sample rod.

The MPMS SQUID VSM dc Magnetometer offers you ≤ 10-8 emu sensitivity with only 4 second data averaging. Thermomagnetic curves were taken by a vibrating sample magnetometer in an external magnetic field of 0.24 T at a heating rate of 10 K/min from room temperature up to 800°C. 3. In a typical setup, the induced voltage is measured with a lock-in amplifier using the piezoelectric signal as a frequency reference. The vibrating component causes a change in the magnetic field of the sample, which generates an electrical field in a coil based on Faraday’s Law of Induction. Sci. for samples of small magnetic moment, large corrections must be made for the magnetic effects of materials which surround the stationary sample.7 A particularly successful vibrating-sample magnetometer is described in this paper.
