How should powerful neodymium magnets be properly store?

Rare earth neodymium magnets is one of the most widely used magnetic materials in the market at present, but at the same time, because of its strong magnetism, easy corrosion, and fear of high temperature, how to store it is very critical. The following are some methods and suggestions for saving/storing neodymium magnets.


The following are some suggestions for proper preservation of neodymium magnets, suitable for various neodymium magnet shapes and applications;

1. Keep neodymium magnets isolated from other magnetic or magnetically sensitive items to avoid mutual interference. This can be done by placing neodymium magnets in separate containers or using magnetic shielding materials.


2. Keep dry: Neodymium magnets are prone to rust, so they should be kept dry. Neodymium magnets are placed in a sealed bag or container, and a desiccant (such as silica gel) can be added to absorb moisture.


3. Keep the indoor ventilation dry, humid environment is easy to make the magnet rust, corrosion.


4. Neodymium magnets are brittle materials that are easy to shatter or break, and care should be taken to avoid them colliding with hard objects when stored, and soft materials can be used to wrap or buffer them.


5. Stay away from high temperatures: High temperatures reduce the magnetic properties of neodymium magnets, so exposure to high temperatures should be avoided.


6. Do not go near magnetic sensitive devices: The strong magnetic field of neodymium magnets may interfere with electronic devices such as computers, mobile phones, magnetic storage media, etc. Be sure to keep neodymium magnets away from these devices to avoid data corruption or equipment failure.


Neodymium magnets should avoid the following storage methods (ways):

In places where the air is too humid, the air circulation is not smooth, and the temperature difference is large, even the products qualified by the salt spray test will produce rust spots if they are stored in a harsh environment for a long time. When the electroplated product is stored in a harsh environment, the base layer will further react with the condensate, resulting in a reduction in the binding force between the base layer and the plating layer, and in severe cases, the base will crack. When cracked, it is very easy to locally powder, and then naturally peel. Therefore, electroplating products should not be placed in a place with high humidity for a long time, and should be placed in a cool and dry place.


When you need to use or move neodymium magnets, you should be careful to avoid pinching your fingers or attracting other objects. It is best to wear gloves to protect your hands when handling neodymium magnets.


In summary, good preservation of neodymium magnets can ensure that they maintain strong magnetism for a long time, avoid damage and interference, and extend their service life, which can better play the magnetic ability of neodymium magnets, and ensure their reliability and effectiveness in a variety of applications.
