Great Experiments Investigating Lenz's Law Effects of Magnetic Orientations Sliding Down a Ramp

Similar to my previous post, here are more great demonstrations of the "Lens' law" effects of different magnetic orientation of a magnet sliding down an aluminum ramp. Interestingly, the magnet takes longest falling down when the poles are perpendicular to the ramp, and fall even slower when the aluminum ramp is thicker. Interesting stuff!
