What Is Demagnetization?

The strength of a magnet, usually measured in gauss or pull, is one factor that determines the effectiveness of a magnetic separator. In the food industry, equipment is exposed to a variety of different temperatures, environments, products, and other circumstances that can affect the magnet's strength. High-quality magnetic separators can retain adequate strength & effectiveness for many years, however, low-quality cheap systems can lose their strength rapidly - despite being 10,000 gauss or higher upon supply! Loss of magnetic strength is referred to as 'demagnetization'. Some of the most common influences of demagnetization include: • temperature, • oxygen absorption, • resonant vibration, • thermal shock, and • rough handling (such as dropping or banging). Once a rare earth magnet's strength is lost, it is lost forever - you cannot 'recharge' these magnets strength as you can a battery.
