Damping vibrations is crucial for precision experiments, for example in astronomy. A new invention uses a special kind of magnets to achieve this — electropermanent magnets. They consist of a permanent magnet and a coil. In contrast to electromagnets, they do not have to be permanently supplied with energy. In contrast to permanent magnets, their strength can be tuned: Whenever necessary, a strong electric pulse is sent through the coil, adapting the properties of the magnet.
