The VSM shaker functions
Know About VSM Shaker Functions
Vibrating Sample Magnetometer (Vibrating Sample Magnetometer, VSM shaker is one of the important methods to measure the magnetic material. It has been widely used in all kinds of ferromagnetic, ferromagnetic and antiferromagnetic and magnetic properties of paramagnetic and diamagnetic materials research. It includes researches such as the rare earth permanent magnet, ferrite materials, amorphous and crystalline materials, superconducting materials, magnetic alloys, compounds and biological protein study and so on. It can measure basic magnetic materials, such as magnetization curve and hysteresis loop, the demagnetization curve, thermomagnetic curves, etc., and obtains the corresponding magnetism parameters, such as saturation magnetization Ms, remanent magnetization, the coercive force Hc, the maximum magnetic energy product, Curie temperature and permeability (including initial permeability), etc. It can measure the samples of powder, granule, film, liquid blocks such as magnetic materials and so on.Here to click sand pump and you can know more about this kind products.
The VSM shaker functions
Materials that VSM shaker can deal with, according to its magnetic classification, it general can have the following five kinds, namely:(1), paramagnetic - this kind of material has independent magnetic moment, in the absence of the external magnetic field under the action of random orientation each other, so they don't show the macroscopic magnetic; While under the effect of outfield, originally separate mixed and disorderly distribution of magnetic moment along the magnetic field orientation will go a certain extent, making this material show the corresponding macroscopic magnetic materials; The stronger the magnetic field, the stronger the macroscopic magnetic, and when the external magnetic field, the macroscopic magnetic will disappear. As for magnetizing field with magnetic susceptibility χ said, H, M for the magnetic moment per unit volume, M = χ H; χ values about 10-3 ~ 10 to 5 orders of magnitude. (2), inverse magnetic (magnetic) resistance - such substance has no intrinsic magnetic moment, but under the action of outside magnetic field it will have induction magnetic M = - χ H, M and H the opposite orientation, so its name has birthed. Χ is very small, it is about 10-4 ~ 10-6 orders of magnitude. When the magnetic field disappeared, macroscopic magnetic will also disappear. (3), antiferromagnetic -- this kind of material is the magnetic moment of two equal and opposite orientation, and synthesis of magnetic moment is zero, making the material has no macroscopic magnetic material. (4), ferrous magnetic - this material has two different sized and reverse coupling magnetic moment together, so they can't completely offset each other, making the class material shows strong magnetic properties, the macroscopic magnetic and magnetic field have become into a complex relationship. (5), ferromagnetism-- such substances within the magnetic moment can be parallel coupled together and show strong magnetic properties, it is the same as ferrous magnetic, macroscopic magnetic and magnetic field can appear very complex relationship.Which kind de-1000 decanter centrifuge do you like best ,here to find the features of it.
People usually call the former three kinds weak magnetic, the latter two classes as the strong magnetism. Strong magnetic materials play an indispensable role in human society, such as the electric power department, the department of information industry, the aerospace field, etc. However, with the progress of human society, many people have asked for more updates for many properties of materials, including magnetic, this causes the people unceasingly doing the related research, explore and improve performance. To do so, it must have reliable physical testing equipment. VSM shaker is the recognized special tests of all kinds of material (material) intrinsic magnetic properties of devices, such as magnetization Ms Sigma (s), Curie temperature, coercive force. And in predicting samples demagnetization factor N, the direction of measurement can be indirectly obtained other relevant technical magnetic parameters, such as: (BH) Max, etc. The other can be judged by measuring the magnetic properties of the sample according to the characteristics of the loop. Due to the perfect VSM shaker functions, low operating cost (except superconducting type), durable, high detection sensitivity, etc. They are widely used in industrial and mining enterprises, universities and research institutions.Getting the quality desander ?
