The strongest permanent magnets in the world are based on a Neodymium-iron-boron alloy, to which praseodymium is often added. These magnets are required for technologies such as electric motors, wind turbines and nuclear magnetic resonance scanners, but are also used in everyday devices such as loudspeakers and headphones. Praseodymium is also used for colouring and decolouring glass. Solid-state lasers and alloys, for example for aircraft construction, are further fields of application.
