When we use powerful magnets, we usually try to prolong the service life of products and equipment, so that they can be used for a long time and reduce costs.
The magnetic force of the magnet will slowly weaken until it disappears during use, so we should master the correct preservation method to extend its service life.
The surface magnetic induction of a powerful magnet is proportional to the size of the very small particles that can be adsorbed. In the battery and pharmaceutical fields, fine iron impurities can also have a great impact, so products with about 12,000 Gauss should be selected. The other fields can be lower. Please store the material of the powerful magnet at moderate temperature and humidity, and store it in an environment that has no effect on the magnetism, so as not to affect its magnetism by the temperature and humidity of the environment.
Generally, the powerful neodymium iron boron permanent magnet will be preserved by surface treatment. Don't blindly think that the environment and humidity have no effect on the magnet. The drier the environment, the longer the magnetic service life of powerful magnets.
When choosing a powerful magnet, we all want to choose a good quality. But now there are many types of powerful magnet products, and the quality is uneven. Therefore, when choosing a powerful magnet, we should be familiar with the structure, function and application of the product, which will help us choose a powerful magnet that suits us.
