What is the strength of the magnet company?
Time:02/15/2019
Whether a magnet finished product meets the production regulations, generally speaking, it has its own strict standards in the Qingjingze magnet manufacturer. The approval standard of each magnet company will be different, but the change is not inconsistent, and the magnetic properties of the magnet are judged. There are three hard standards in the magnet production industry, namely remanence Br, coercivity Hc and magnetic energy product Bhmax. Let's take a look at what the standards of these three methods represent.
 
The first remanence Br, which refers to the magnetic flux density of the Qingjingze magnet product after removing its own magnetic field in the state of saturation, its unit is gauss, which means that the magnet can be used during use. The strength of the magnetic field generated by the outside world is different, and the magnets of different types of magnets of the magnet company are different. In general, the current production process can accurately control the production of various types of magnets to achieve the specified remanent Br value. At the time of purchase, the user can directly inspect the product through the inspection instrument.
 
 
 
The second is the coercive force Hc standard, which refers to placing the finished magnet in a magnetic field that is completely opposite to itself. When the strength of the reverse acting magnetic field is increased to a certain extent, the magnetic force of the original magnet product itself. Disappeared. Magnet manufacturer magnet products resist the force of the reverse magnetic field, which is the coercive force Hc of the magnet. Its unit is oersteds, which represents the anti-demagnetization ability of the magnet itself. This is very important in the production process of magnet manufacturers. The service life of the product.

The third criterion is the magnetic energy product BHmax, which represents the magnetic field capability of the magnet in a specified unit volume of product. It is a very important criterion for the magnet company to measure the magnetic properties of the magnet, and represents the magnetic capacity of the product itself. How many.
