The duration for which magnets stay strong depends on several factors, including the type of magnet material, usage conditions, and maintenance practices. Here are some general guidelines for different types of magnets:
It's important to note that these are general guidelines, and the actual lifespan of a magnet can vary based on factors such as magnet quality, usage conditions, temperature variations, and exposure to other influencing factors. Regular maintenance and proper handling can help prolong the magnet's effective lifespan. If you require consistent magnetic performance in your application, it's a good idea to periodically test the magnet's strength and replace it if necessary.
Lower temperatures, specifically colder temperatures, can make certain types of magnets temporarily stronger. This effect is most notable in neodymium-iron-boron (NdFeB) magnets, which are sensitive to temperature changes. When exposed to colder temperatures, the magnetic strength of neodymium magnets can increase.
The heat resistance of magnets varies depending on the type of magnet material. Some magnet materials are more heat-resistant than others, while others can be significantly affected by elevated temperatures. Here's a general overview of the heat resistance of common magnet materials:

Neodymium cylinder magnets are strong, versatile rare-earth magnets that are cylindrical in shape, where the magnetic length is equal to or larger than the diameter. They are built for applications where high-magnetic strength is required in compact spaces and can be recessed into drilled holes for heavy-duty holding or sensing purposes. NdFeB rod and cylinder magnets are a multi-purpose solution for industrial, technical, commercial and consumer use.
Magnetic cylinder magnets, represent a popular shape of Rare earth magnets and perment magnets. Cylinder magnets have a magnetic length which is larger than their diameter. This enables the magnets to generate very high levels of magnetism from a relatively small surface pole area.
These magnets have high 'Gauss' values because of their greater magnetic lengths and deep depth of field, making them ideal for activating reed switches, Hall Effect sensors in security and counting applications. They are also ideal for educational, research and experimental uses.
