"Webb22 dec. 2024 · In contrast to purely mechanical brakes eddy current brakes work only if there is motion. I.e. braking force depends not only on the magnetic field but also on the speed of the conductor moved through the field. They don't brake at all if everything is at rest; no matter how strong the field is (that's why they often are ideal for dampening). " - Small eddy current brake
