The magnet in the magnetic perfume cap is sintered NdFeB magnet. The magnetic perfume cap magnet is used very much in a year. Many magnet manufacturers in Zhejiang Province and Guangdong Province have converted millions of magnets, and the market competition in this field is very fierce In this case, some magnet manufacturers have applied low cost sintered NdFeB magnets and bonded magnets to magnetic perfume bottles. For low cost sintered NdFeB magnets, their life and tensile force will be much lower than that of ordinary magnets.
Considering the ergonomic design, the magnet will be magnetized to 4 poles The 4 pole magnet can also provide enough tension to avoid the dropping of the magnetic perfume cap. For the same magnet, the multi pole pull will be higher than the simple axial magnetization, so customers can find 8-pole and 16 pole magnets in the low-cost sintered NdFeB magnet. The magnetization process is the productivity limit of magnetic perfume covered magnets over the past few years.
