A vibrating-sample magnetometer (VSM) (also referred to as a Foner magnetometer) is a scientific instrument that measures magnetic properties. Simon Foner at MIT Lincoln Laboratory invented VSM in 1955 and reported it in 1959.Also it was mentioned by G.W. Van Oosterhout and by P.J Flanders in 1956. A sample is first magnetized in a uniform magnetic field. It is then sinusoidally vibrated, typically through the use of a piezoelectric material. Commercial systems use linear actuators of some form. 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.
