For those old drivers who use magnets for many years, they basically know the characteristics of the powerful magnets and the size of the magnetic products they need. But for some companies that have not used magnets, they don't know much about the powerful magnets. So what are the problems to be paid attention to in the design of a powerful magnet?

At present, in the field of magnetic products, many people call different types of magnetic products magnets. Let me briefly explain how to strengthen the magnetic force of NdFeB magnet. The two ways to strengthen the magnetic magnetism of NdFeB strong magnet are two aspects of size and material, size: if the contact area is large and the thickness is thinner, then increasing the thickness of the magnet will have a great effect on increasing the magnetism. If the contact area is small and the thickness is relatively thick, increasing the contact area of the magnet will directly change the magnetic force. From the material of magnets, Nd-Fe-B magnetic materials will also be divided into many material grades. If the material is not the best, and space can not change the size of the mag

Small magnets have strong absorbability and are now applied to products of all walks of life. They play a very important role, so how do magnets make them? In fact, the magnet itself is not a monolithic component of the main ingredients, such as neodymium, iron, boron and other raw materials, and then mixed and sintered, so that the raw materials of our magnets are made well. The raw materials of the magnet are mainly two types of circular and square, and what size is needed to cut out of the large blank material by the slicer After cutting, it is electroplated after surface treatment. The magnet plating is to protect the magnet from corrosion and rust, and has nothing to do with magnetic force. After the plating, the magnet is not magnetic. Magnetizer is needed to magnetize the magnets

Rare earth praseodymium, neodymium and other raw materials after a sharp increase in 7.8 months, the subsequent price all the way down. The market turnover and activity are very low, and the less people are watching, the less people will buy. After a few months, many industry insiders predict that after falling to a certain bottom, the market reader will appear, but they do not know where the bottom is. After two days of price stabilization, it is said that the market activity began to rise yesterday, the enquiry and turnover have risen, and even some praseodymium and neodymium factories did not offer quotations yesterday.

Since this year, the price of NdFeB strong magnet raw materials has been rising, causing many of our end users to call hard, and what is the price of the strong magnet in the end? There are several big aspects of the price rise this year. On the one hand, it is the state control and storage. On the one hand, the government has stopped some irregular raw material separation manufacturers on the one hand, and on the other hand, it is the stability of our market demand. A combination of several factors has led to the rising price of magnets this year.
