hey guys, I've been given an assignment on the topic of eddy currents and magnetic induction. We have been given info that when a magnet slides down an incline over a magnetic sheet, the eddy currents in the metal acts as a braking mechanism (lenz's law).
I've done some research and what i don't get is how why there is eddy currents involved when there is no voltage or emf being put into the metal sheets??
Also why does factors such as different metals, thickness affect the speed of the magnet sliding down??
thanks in advance.
