Information

Vibrating sample magnetometer VSM-175 manufacturers tell you that the vibrating sample magnetometer is referred to as VSM, which is an important part of measuring the magnetic properties of materials. It is widely used in various ferromagnetic, ferrimagnetic, antiferromagnetic, paramagnetic and diamagnetic materials. Among them, it includes magnetic research on dilute permanent magnet materials, ferrite materials, crystalline and quasicrystalline materials, superconducting materials, composites, compounds and matter eggs, etc.

Discount Vibrating sample magnetometer VSM-175 from China manufacturer
Vibrating sample magnetometer VSM-175 manufacturers tell you that the vibrating sample magnetometer is mainly composed of electromagnet system, sample forced vibration system and signal detection system.
The manufacturer of Vibrating sample magnetometer VSM-175 tells you that when the power output of the oscillator is fed to the driving coil of the vibrating head, the vibrating head can drive the vibrating rod fixed on the driving coil to vibrate with equal amplitude at the frequency of ω. The sample under test in the magnetization field H vibrates the same; in this way, the dipole field produced by the magnetized sample in space will vibrate in the same way relative to the stationary detection coil, resulting in a frequency ω in the detection coil. Vibrating sample magnetometer VSM-175 manufacturer tells you that the voltage output of the oscillator is fed back to the lock-in amplifier as a reference signal; after feeding the above-mentioned induced voltage with a frequency of ω to the lock-in amplifier in the normal operating state ( The so-called normal operation, that is, the measured signal of the lock-in amplifier and its reference signal have the same frequency and phase), after the amplifier and phase detection, a DC voltage V J out that is positive to the total magnetic moment of the measured sample is output. Corresponding to this, there are A DC voltage V H out that is positive to the magnetizing field H (that is, the voltage on the sampling resistor or the output voltage of the meter), and the two corresponding voltages are graphed to obtain the hysteresis loop (or magnetization) of the sample under test. curve).
Vibrating sample magnetometer VSM-175 manufacturers tell you that many intrinsic magnetic properties of the tested sample can be obtained by predicting the volume, mass, density and other physical quantities of the tested sample. If the demagnetization factor N of the sample can be known, the magnetic induction of the material (material) and the technical hysteresis (magnetization) curve of the internal magnetization field Hi can be obtained from the above measured curve, and many technical magnetic parameters such as B r , H c , (BH) max , etc.
