NdFeB rectangle magnets, known for their superior magnetic properties, require careful handling and storage to preserve their magnetic integrity. 

Storage Conditions: Temperature and Humidity Control

NdFeB rectangle magnets are sensitive to temperature and humidity. They should be stored in a cool, dry place to prevent demagnetization and corrosion. High temperatures can reduce their coercivity, while humidity can lead to corrosion.

Protection from External Magnetic Fields

To avoid unwanted magnetization or demagnetization, NdFeB rectangle magnets should be stored in a location shielded from external magnetic fields. This prevents interference that could affect their magnetic properties.

Handling Precautions

Avoiding Physical Contact with Other Magnets

Direct contact with other magnets can lead to a loss of magnetic properties due to interaction between magnetic fields. It is advisable to handle NdFeB rectangle magnets with non-magnetic tools and store them separately to avoid such interactions.

Minimizing Mechanical Stress

Mechanical stress can damage the magnetic structure of NdFeB rectangle magnets. They should be handled with care to avoid dropping or applying excessive force, which can lead to chipping or cracking, thereby affecting their magnetic properties.

Proper Packaging

Using appropriate packaging materials can provide an additional layer of protection. Anti-static materials can prevent electrostatic discharge, which can also affect the magnetic field. Additionally, cushioning materials can protect against physical damage during transportation or storage.

Maintenance and Inspection

Regular inspection of stored NdFeB rectangle magnets can help identify any signs of demagnetization or physical damage early. This includes checking for signs of corrosion, physical damage, or changes in magnetic performance.

Protective Coatings

All NdFeB magnets should have some form of protective coating to minimize and ideally prevent corrosion. The default protective coating is Nickel Copper Nickel (NiCuNi), but other options like Zinc (Zn), Nickel-Copper plus Black Nickel, and various epoxy coatings are also available. These coatings not only protect against corrosion but also prolong the magnet's lifetime when used in good environmental conditions.

Proper storage, handling, and maintenance are crucial for preserving the magnetic integrity of NdFeB rectangle magnets. By controlling temperature and humidity, shielding from external magnetic fields, handling with care, and using protective coatings, the longevity and effectiveness of these powerful magnets can be preserved. Regular maintenance and inspection further ensure that any issues are identified and addressed promptly, keeping the magnets in optimal condition for their intended applications.
