تماشای ویدئو Watch what happens when a magnet falls thru a copper pipealuminum pipe. از آی-ویدئو

Looks like the magnet is falling thru oil or in slow motion. It is actually producing electricity and slowing the magnet down. I use a 3/4" x 1" n52 magnet. Makes a easy science project. Here is a link to magnets on ebay: https://rover.ebay.com/rover/1/711-53200-19255-0/1?icep_id=114
