When a sample is placed within a homogeneous magnetic field and set into vibrational motion, it induces an electromotive force (EMF) in nearby pickup coils. The magnitude and phase of this induced EMF is directly proportional to the magnetic moment of the sample. By measuring these signals, the VSM can determine the magnetic …
Vibration is the movement or mechanical oscillation about an equilibrium position of a machine or component. It can be periodic, such as the motion of a pendulum, or random, such as the movement of a tire on a gravel road. Vibration can be expressed in metric units (m/s 2) or units of gravitational constant g, where 1 g = 9.81 m/s 2.
Achieving this level of precision requires rigorous engineering to isolate the platform from external disturbances such as vibrations, magnetic fields, and electrical …
