Preventing entrapment: NdFeB magnets have a strong magnetic force and can be quickly attracted together, which can cause serious entrapment injuries if a finger or other body part is accidentally caught between two magnets.

Avoid shattering injury: NdFeB magnets are relatively fragile and may shatter if subjected to strong impact. Broken magnets can release sharp fragments that can cause injury. Therefore, great care should be taken when using magnets.

Preventing allergies: A small percentage of people are allergic to nickel, and neodymium-iron-boron magnets are usually plated with a nickel layer. People who are allergic to nickel may experience allergic reactions, such as skin redness and rashes, when exposed to magnets for long periods of time.

Stay away from electronic devices: The strong magnetic field of NdFeB magnets may interfere with or damage electronic devices, such as cell phones, computers, and televisions. Therefore, when touching the magnet, you should make sure it is far away from these electronic devices to avoid damage to the equipment.

Pay attention to the storage environment: NdFeB magnets are prone to rust or corrosion in a humid environment, which can reduce the magnetic strength. Therefore, when touching or storing the magnet, you should make sure it is in a dry environment and avoid contact with corrosive substances such as acids and alkalis.

Child safety: NdFeB magnets are not toys and should not be touched by children. Small magnets can pose a choking hazard, and if multiple magnets are swallowed, they can interconnect through the intestinal wall, leading to serious health risks.

In summary, safety precautions need to be taken when touching NdFeB magnets, including preventing entrapment, avoiding shattering injuries, preventing allergies, keeping them away from electronic devices, paying attention to storage environments, and ensuring child safety.
