Many friends may have such a question, do magnets with the same performance and volume have the same suction force? It is said on the Internet that the suction force of an NdFeB magnet is 640 times its own weight. Is this credible?

3C consumer electronics products mainly include six categories: mobile phones, tablets, laptops, watches, earphones and wireless charging devices. Taking Apple products as examples are iPhone, iPad, Mac, Watch, AirPods, and MagsafeParts.

In the packaging industry, we can often find the application of NdFeB powerful magnets. Magnets play an important role in packaging systems. Packaging manufacturers and designers, as well as marketing agencies, are unanimous in their preference for magnets when packaging their products. The main function of the magnet in the packaging gift box is to seal the package.

Magnetic materials are materials that can react to magnetic fields in a certain way. According to the degree of magnetization, they can be divided into permanent magnet materials and soft magnetic materials. Permanent magnet materials, also known as hard magnetic materials, are mainly characterized by their high magnetic property and high coercivity. After removing the external magnetic field, they can still maintain high magnetism for a long time. Common permanent magnet materials are divided into aluminum-nickel-cobalt permanent magnet alloy, fe-chrome-cobalt permanent magnet alloy, permanent magnet ferrite, rare earth permanent magnet material and composite permanent magnet material, etc.
