Electromagnetic brake

With the fall of the ring from the top of the aluminium rod, power acts on the ring, which makes the circle do not fall as free fall, but decreases very slowly. This power can be felt when pulling the ring upwards as if stirred by the sticky surface. Supplied with a set of metal circles.

Power supply: 220 V

Material: metal, neodymium magnet

Dimensions (cm): 100 x 20 x 20
