NdFeB strong magnet is the most widely used magnetic material in the field of modern science and technology. It has the advantages of strong magnetism, small size and light weight. However, if it is not handled and maintained properly during use, problems such as magnetic drop and demagnetization may occur. The following article will introduce some methods with good degaussing effect to help you better protect and use the strong magnetism of NdFeB.
First, use the environment correctly. Strong magnetic fields will have a great impact on NdFeB magnets. To truly achieve the effect of maintaining strong magnetism, they need to be used in a suitable environment. For example, it is necessary to avoid being affected by high temperatures, strong heat sources, radioactive sources, etc., as well as to avoid encountering magnetic and non-magnetic materials rubbing against each other, causing magnetism to weaken. Therefore, when using NdFeB strong magnets, try to avoid the influence of these factors and ensure that they remain in a stable condition.
Second, maintain the magnet properly. Proper maintenance before and after use will allow NdFeB magnets to exert their best performance. Make sure the surface of the magnet is clean. Do not apply or write any marks or engravings on the surface of the magnet to avoid wearing or damaging the surface of the magnet and affecting the performance of the magnet. In addition, when NdFeB magnets are stored, avoid contact with moisture or corrosive gases and chemicals. The magnets can be stored in magnetically sealed small bags or boxes to avoid long-term exposure to the air. Their magnetism gradually decreases.
Third, appropriate handling methods. When you first start using NdFeB magnets, you should handle them appropriately, such as magnetic treatment, that is, let the magnets be magnetized and kept for a sufficient time, which can make the magnets achieve the best magnetic properties.
