Dysprosium is used as an alloy component in a whole range of technologies. These include permanent magnets, such as those found in the generators of wind turbines and the drive motors of electric cars. Dysprosium increases coercivity, allowing magnets to retain their adhesive force for longer. At the same time, this additive increases the usable temperature range of the magnet. While this is up to 80 degrees Celsius for neodymium-iron-boron magnets, it can be extended to over 200 degrees by adding dysprosium. Only then does demagnetisation begin. The element is also used in nuclear reactors or in the manufacture of sensors.
