Question

On what factors does the damping coefficient of an eddy current damping depends

Answer 1

The relative movement of the magnets and the conductor causes the conductor to undergo motional eddy currents. Since the eddy currents produce a repulsive force that is proportional to the velocity of the conductor, the moving magnet and the conductor behave as a viscous damper

Answer 2

Explanation:

The damping coefficient depends on the shape of the body when the effect of the fluid on the solid is considered. For instance, the viscous effect of the air/water the mass vibrates in.
