Lenz's Law Short version. magnets drop through copper tube.

Thanks once again Mathiew for all your hard work! :-)
Great job in editing much data into one short video, wow!

Do opposing/repelling magnets fall slower through a copper tube and more details. Let's glue them together :-) The magnetic fields of the permanent magnet penetrate into the walls of the copper tube, and inside that wall, Eddy currents are created, and those Eddy currents have their own fields that then oppose the magnet falling, slowing it down.
