How Long Can the General Suction of Strong Neodymium Bar Magnets Be Maintained?

Strong neodymium bar magnets are mainly composed of three materials: neodymium, iron, and boron. Of course, they contain other elements, but the ingredients of different products are different. The magnitude of the magnetic force depends on the ratio of these key materials. Therefore, in the process of communicating with customers, a professional magnet manufacturer must provide magnets with suitable magnetic force according to the actual use requirements put forward by the customers to ensure the normal use of the product.

Ⅰ. Factors affecting the magnetic attraction of strong neodymium bar magnets

Many external conditions restrict the suction force of the strong neodymium bar magnet. The use of occasion, temperature, humidity and other factors will continuously lose the suction force of the strong magnet, and the installation method is also an essential factor.

For example, strong magnets of the same size have different adsorption capacities for the same object because of the various grades. For magnets of the same size, we also use the same grades, but when the same object is adsorbed on the front and side, the tested suction is different. The vertical adsorption force produced by the vertical installation is different from the horizontal adsorption force produced by the horizontal structure. Therefore, if you want to buy a suitable strong neodymium bar magnet, you still need to go to a regular factory to ensure the stability of the material and understand the correct reference basis for the size of the suction.

Ⅱ. Suction time of strong neodymium bar magnet

The industry has also discussed the magnetic retention time of strong magnets for many years. Due to the use of strong magnet products in a wide variety of environments, methods, and types, under normal circumstances, the attractive force of strong magnets will not be affected by the outside world. That is why it dubbed the permanent magnet.

However, under special conditions of use, such as salt spray corrosion, it will cause very large external damage to the strong magnet itself, and the magnetic force will definitely be affected, and the magnetism will inevitably be lost over time. Therefore, in a special environment, it is necessary to select raw materials suitable for the special environment and suitable electroplating protection to ensure the permanent attraction of the strong neodymium bar magnets.
