The magnet is arising a counter emf (i.e. voltage, which produces cutting-edge which continuously has a magnetic field round it) in each and each and every pipe because it strikes, the counter emf is slowing the move of the magnet's fall. it is going to fall quickest through the plastic as percentwon't habit electrical energy and consequently can't produce an opposing magnetic field. sturdy success.
