Theory of Operation of Vibrating Sample Magnetometer Systems If a material is placed within a uniform magnetic field H, a magnetic moment m will be induced in the sample. 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. 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. Sci. The Vibrating Sample Magnetometer is a sensitive and versatile instrument for study of magnetic moments in different magnetic materials as a function of magnetic field and temperature.

Simon Foner at MIT Lincoln Laboratory invented VSM in 1955 and reported it in 1959. Vibrating Sample Magnetometer(VSM): PAR 155 The magnetic properties of solids are very important, and attempts to understand them have led to a deep insight into the fundamental structure of many solids, both metallic and non- metallic. In vibrating sample magnetometry (VSM) the sample is attached to a nonmagnetic rod, which is oscillates or vibrates in a gap between (pairs of) fixed coils (pick-up coils) The idea behind this procedure is that the 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. technique and subsequent analysis to produce the FORC diagram, which reveals data not readily discerned from the hysteresis loop. When a sample vibrating at a certain frequency is placed between two electromagnets an e.m.f is induced according to the amount of magnetization the sample undergoes due to the change in orientation of the magnetic domains (molecular magnets) which produces a net magnetic moment in the sample under study. VSM involves vibration of a magnetic material within a uniform magnetic field H, generating an electric current in properly placed sensing coils. 30 548–57 [2] Howling D H 1956 Simple 60-cps Hysteresis Loop Tracer for Magnetic Materials of High or Low Permeability Rev.
