neodymium-iron-boron (NdFeB) magnets

The life of a magnet is affected by a number of factors, including the type of magnet, the environment in which it is used, how it is maintained, and the conditions in which it is stored. This article will detail how these factors affect magnet life and provide some suggestions for extending magnet life. Magnets can be roughly divided into two categories: permanent magnets and electromagnets. Permanent magnets, such as neodymium-iron-boron (NdFeB) magnets, are by far the most commonly used and are stable and strong. Electromagnets, on the other hand, require a constant supply of electric current to maintain a magnetic field. Environment of use The environment in which a magnet is used has a direct impact on its life. Temperature, humidity, chemicals and mechanical vibration in the environment can all negatively affect the magnet's magnetic properties. Temperature: High temperatures are one of the main factors that weaken the magnet's magnetic properties. Generally speaking, the maximum operating temperature of permanent magnets ranges from 80°C to 200°C. Beyond this range, the magnetism will be permanently weakened. Humidity: Increased humidity can accelerate the corrosion process of magnets, especially for those with inadequate surface protection. Chemicals: Chemical corrosion is also capable of damaging the structure and magnetic properties of magnets, especially in acidic or alkaline environments. Magnets can have a very long life, but the exact life depends on their type, the environment in which they are used, and how well they are maintained. By understanding these factors and taking proper protective measures, the life of a magnet can be effectively extended. For those applications where magnetism needs to be maintained over a long period of time, it is important to select high quality magnets and maintain them properly.
