One of the important parameters of permanent magnet materials is the stability of magnetism, which mainly refers to the influence of internal and external factors on the magnetic properties of permanent magnet materials after magnetization: temperature, time, chemical corrosion, mechanical vibration and shock, radiation, etc. The most significant impact on the stability of neodymium permanent magnet materials. The three parameters to measure magnetic performance are: remanence, coercivity, and maximum magnetic product energy. First, let's understand the concept of related parameters.

The bonded NdFeB magnets are molded by injection molding, so they contain adhesives, and the density is generally only 80% of the theoretical value. The sintered neodymium magnet is heated at a high temperature through a complicated process. Therefore, the bonded NdFeB magnet is attenuated by about 30% compared with the sintered NdFeB magnet. For example, the coercivity of our sintered magnet has reached 33AH. Therefore, sintered NdFeB is generally used in a wider range than bonded NdFeB.The degree of shrinkage depends on the thickness and shape of the product. The typical dimensional tolerance is: ±0.05mm. Therefore, the application range of sintered magnets is wider than that of bonded magnets.

Our ferrite flexible rubber magnet can be coiled to 1/4" radius without breaking. There are "Isotropic" and "Anisotropic" in the flexible rubber magnet. The Isotropic rubber magnet normally is to be magnetized with multipoles magnetization on one side only and the Anisotorpic one has magnetics on both side. Based on customer's demand, the rubber magnets can be laminated by colorful PVC, adhesive tape or colorful printing. The attractive face is treated with UV coating which can protect the products surface. We also can supply. Magnetic Paper " for A4 size, which made from rubber magnets and laser paper. The thickness just has 0.3mm which can be printed by any printing machine!

The application of neodymium permanent magnets in electronic products is also innovative, and magnets are also full of charm! Therefore, friends should also pay attention to the mobile phone because of these functions, it is best not to place the mobile phone in a strong magnetic environment, so as not to affect the function.

The magnets we know are divided into permanent magnets and non-permanent magnets. The permanent magnet itself can also be a natural product, or it can be manufactured artificially.
Magnets have a very peculiar function. It can attract materials such as iron and nickel. It plays a very important role in industrial society. The earliest words people use are dug out from nature, but the magnetism of that kind of magnet is very weak and the magnetism is not stable enough. On the basis of this time, a magnet was made by groping step by step. Do you know how magnets are made?

As far as magnetic materials are concerned, strong magnetic neodymium disc magnet products will become non-magnetic after reaching a certain high temperature. Generally, magnetic materials have a maximum temperature value Tc. Above this temperature, strong magnets will move violently under high temperature conditions, and there is no order in the placement of atomic magnetic moments. Below this temperature, the atomic magnetic moments are placed neatly and regularly, spontaneous magnetization occurs, and the object becomes a magnetic iron material.

The biggest application of neodymium is to make magnets with excellent performance. This kind of neodymium magnet is called neodymium iron boron magnets (NdFeB magnets), which is the strongest permanent magnet that has been found. This kind of magnet is extremely strong.

What a fun magnet - fishing magnet What is a fishing magnet Fishing Magnet also called Magnet fishing,magnetic fishing. Is searching in outdoor waters for ferromagnetic objects available to pull with a strong neodymium magnet.
