Lets say i have a magnetic pendulm, (basically a barmagnet suspended from a with a string tabletop) and a conductor at the bottom.
The conductor will ofcourse have Foucault currents generated in it, and this due to conservation of energy, will slow down the swinging of the pendulum, reducing the "amplitude" of its swing.
But my question is, will it also reduce the period it takes for the pendulum to oscillate?
Is the rate at which the amplitude decays, proportional to the decrease in speed so as to preserve the time taken?
