A damping apparatus is disclosed comprising at least one pair of magnets and a conducting member. The at least one pair of magnets define a gap therebetween. The conducting member is coupled to a payload and positioned within the gap. The conducting member is configured to vibrate in response to a vibration of the payload. The conducting member comprises a conducting material. Vibration of the conducting member generates eddy currents in the conducting member, and the eddy currents generate a frequency-dependent damping force. The frequency-dependent damping force is adjustable based on the conducting material and a thickness of the conducting member. The conducting material and the thickness are selected to adjust the frequency-dependent damping force.
