Powerful magnet daily hazard prevention: Three risk response solutions

When using neodymium iron boron magnets, the primary safety risk is entanglement. Neodymium iron boron magnets have strong magnetic force. When two magnets approach each other or when a magnet gets close to a ferrous object, they will quickly attract and generate a significant instantaneous impact force. This force is strong enough to entangle fingers or skin, and in severe cases, it may cause bruising or even fractures. To avoid such situations, it is recommended to wear gloves when handling larger-sized or more powerful neodymium iron boron magnets, and try to maintain a safe distance between the magnets and between the magnet and metal objects. When storing, use non-magnetic materials such as plastic sheets or cardboard to separate the magnets, reducing the possibility of accidental attraction. 

Apart from physical damage, neodymium-iron-boron magnets also face the risk of performance degradation, namely demagnetization. High temperatures and severe impacts are the main causes of demagnetization of neodymium-iron-boron magnets. Generally speaking, the temperature limit for ordinary neodymium-iron-boron magnets is around 80 degrees Celsius. If they are exposed to high temperatures for a long time or suffer from strong impacts during operation, the magnetic force may decrease. Therefore, when using neodymium-iron-boron magnets, one should stay away from heat sources, avoid prolonged direct sunlight, and handle them gently during installation, removal, or transportation to reduce unnecessary impacts. For situations requiring high temperature resistance, one can choose neodymium-iron-boron magnet products with higher temperature resistance levels. 

Another common problem is corrosion. The main components of neodymium iron boron magnets include iron and neodymium. These metals are prone to oxidation in a humid environment, resulting in rusting. Sweat, moisture, or prolonged exposure to a high-humidity environment can accelerate the corrosion process of neodymium iron boron magnets, not only affecting the appearance but also weakening the magnetic force. To extend the service life of neodymium iron boron magnets, it is recommended to choose products with surface coating protection, such as nickel plating or zinc plating. After use, clean the surface with a dry cloth in time and store it in a dry and ventilated environment. 

Overall, when used and stored correctly, neodymium iron boron magnets can function more safely and stably.
