VSM by LDJ Electronics

Model# 9100-1

A fine example, super-clean inside and out. Shows absolutely no wear, and appears new.

A rare opportunity to buy this lab equipment at a huge savings!

A Vibrating Sample Magnetometet, or VSM, is a scientific instrument that measures magnetic properties. A sample is placed inside a uniform magnetic

field to magnetize the sample. The sample is then physically vibrated sinussoidally, through the use of piezoelectronic material. Commercial systems

use linear attentuators of some form and historically the development of these systems was done using modified audio speakers, though this approach

 was dropped due to the intereference through the in-phase magnetic noise produced, as the magnetic flux through a nearby pickup coil varies

sinusoidally. 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 a typical setup, the induced voltage is measured through the use of a lock-in amplifier using the piezoelectronic signal as its reference

signal. By measuring in the field of an external electromagnet, it is posiible to obtain the hysteresis curve of a material.
