The benefits and effects of powerful magnets

The benefits and effects of powerful magnets

What is a magnet? It's ndfeb. Compared to ferrite, aluminum-nickel-cobalt and samarium cobalt, ndfeb's magnetic properties exceed those of other types. Ndfeb can absorb its own weight, which is known by outsiders as a powerful magnet.


It is 640 times the weight, so NdFeB Magnet is an object or material that can generate a magnetic field and has the characteristics of attracting ferromagnetic materials such as iron, nickel, cobalt, etc. Traditionally, it can be divided into "permanent" and "non-permanent" magnets.


Permanent magnetism can be a natural product, also known as a natural magnet, or it can be manufactured artificially. Non-permanent magnets, on the other hand, lose their magnetism.


Naturally magnetized stone in nature is called "magnet". The stone can magically pick up small pieces of iron and always point in the same direction after swinging at will. Early navigators used these magnets as their first compasses to navigate the sea.


After development, today magnets have become essential functional materials in our lives. Through advanced powder metallurgy process, the alloy of different materials can achieve and exceed the effect with the magnet, but also can greatly increase the magnetic force.


Magnet types are as follows: it should be called magnetic steel, English Magnet, magnetic steel is now mainly divided into two categories, divided into soft, hard magnetic; Soft magnetism includes silicon steel sheet and soft magnetic core; Hard magnetic includes aluminum-nickel-cobalt, samarium cobalt, ferrite and ndfeb, among which, the more expensive is samarium cobalt magnetic steel, the cheaper is ferrite, high performance is ndfeb, but stable performance, temperature coefficient is excellent is aluminum-nickel-cobalt, users can choose different hard magnetic products according to different needs.


How to define the properties of a magnet?


There are mainly the following three performance parameters to determine the performance: remanent Br: after the magnet is magnetized to technology saturation and the outer magnetic field is removed, the retained Br is called residual magnetic induction intensity.


Coercivity Hc: to reduce the magnet B which is magnetized to the saturation of the technology to zero, the required strength of the reverse magnetic field is called magnetic sense coercivity, or coercivity for short.


Magnetic energy product BH: represents the magnetic energy density established by the magnet in the air gap space (ji space), that is, the magnetostatic energy per unit volume of the air gap. Since this energy is equal to the product of the magnet, it is called the magnetic energy product.


The product of Bm and Hm, so the magnetic field: the space that exerts magnetic effect on magnetic ji is the magnetic field.


Surface magnetic field: the intensity of magnetic induction at a specified location on the surface of a permanent magnet.


How to choose a magnet?


Before deciding which magnet to choose, it should be clear what role it needs to play.


Main functions: moving, fixing or lifting objects.


Desired shape: wafer, circular, square, tile, or special shape.


Required dimensions: length, width, height, diameter, tolerance, etc.


Required suction, expected price and quantity, etc.


The process of making high magnetic materials is very slow. Ferrite, rare earth, samarium cobalt, and neodymium iron boron were produced. At this point, the physical magnetic science and technology has been rapidly developed, and the strong magnetic materials have also made the components small. In the later stage, the independent combination of 13000GS rare earth strong magnets broke the industry precedent, and was soon popularized in the industry. The rare earth magnetic industry ushered in a new world of rapid development.


Xiamen yongling magnet co., LTD is a research and development, production and sales enterprise. Main production and marketing of the same sex rubber magnets (magnetic products); It is widely used in electrical machinery, electronics, electrical appliances, toys, health care and other fields. At the same time in the production of large squares, large rings, cutting and so on also have technology and equipment accumulation. After r & d, we with excellent quality, perfect after-sales service, the company's products are exported to the mainland and other regions, deeply loved by the majority of users.
