Vibration Sample Magnetometer

Main Function of Vibration Sample Magnetometer

Vibration Sample Magnetometer

The VSM (also named M-H CURVE Hysteresis Graph TEST SYSTEM ) can be used for the measurement of the basic magnetic properties of the magnetic materials. Such as the Hysteresis loops of the materials, Magnetization curve, Warming Curve , Warming /Cooling curve, Cooling curve and the changes of the temperature as time goes away , then we will get some Magnetic parameters such as the Saturated strength of the magnetization, the left strength of the magnetization , Coercive force, the Max of Magnetic energy product,the Curie temperature and the Magnetic conductivity(the Initial Magnetic conductivity is included ). It can also measure the magnetic materials such as the powder, the particles, the films, the liquid and the massive.

The VSM can measure the changes of magnetic with the changes of temperature from -196℃ to 900℃.
