A magnet tool represents an investment for a workshop. Although it might not be as expensive as diamond tools, a magnet tool must be properly taken care of to protect the investment and yourself. The last thing you want when moving a heavy work piece is for the magnet to fail. There are things that can be done to increase the life magnet tools.
Like any material, magnets are not immune to harsh environmental conditions. They are vulnerable to temperature and moisture. A magnet can lose its magnetic charge when exposed to a certain temperature. The temperature at which magnets can become demagnetized is known as Curie temperature. The curie temperature varies depending on the type of a magnet. The common ferrite magnets become demagnetized when exposed to temperatures over 460° Celsius. Avoid storing a magnet tool in places that have the tendency of becoming very hot.
Most magnets are made of materials that can corrode when it comes contact with water. Water vapor in humid air can cause magnets to corrode. Ensure that the storage area for the magnet tools has the suitable humidity.
Aside from temperature, there are other causes of demagnetization. Placing two different magnets near each other can cause the weaker magnet to lose its magnetic charge. There are special magnet keepers that are ideal for storing magnets. These magnet keepers help protect magnets from conditions that can have adverse effect on its performance.
