Vibration Sample Magnetometer Educational Prototype

The principle of VSM involves placing the sample in a stable magnetic field, causing the sample to vibrate in a small range relative to the detection coil, thereby generating a signal proportional to the magnetic moment of the sample. This signal is then amplified, its electromagnetic characteristics detected, and converted into a voltage signal, known as VSM. VSM boasts strong adaptability, high sensitivity, accuracy, and ease of use, and is widely used in magnetic material research. It is a fundamental magnetic measurement method commonly used in laboratories and factories.

In research and production practices, magnetic measurement devices that can study and test the magnetism of various materials are often required, especially those with high adaptability, sensitivity, accuracy, and convenience. With the advancement of science and technology, there is a higher demand for automated and intelligent measurement equipment. VSM meets these requirements. VSM is a novel magnetic measurement device developed based on induction, alongside modern electronic technology. The principle of VSM involves placing the sample in a stable magnetic field, causing it to oscillate in a small range relative to the detection coil, thereby producing a signal proportional to the magnetic moment of the measured sample. This signal is then amplified, its electromagnetic characteristics detected, and converted into a voltage signal, known as VSM. VSM features high adaptability, sensitivity, accuracy, and ease of use, and is widely used in material magnetism research. It is a basic magnetic measurement method commonly used in laboratories and factories.

I. Main Functions

VSM can be used to measure the basic magnetic properties of magnetic materials. Based on the hysteresis loop, magnetization curve, heating curve, heating/cooling curve, cooling curve, and time-temperature variation of the material, magnetic parameters such as saturation magnetization, coercivity, magnetic energy product, Curie temperature, and electrical conductivity (including initial electrical conductivity) are obtained. It can also measure magnetic materials in powder, particle, film, liquid, and bulk forms.
