The magnetic damping ring

Specification: 400 mm * 600 mm;The main display device installed on the plate before and after the two pieces of acrylic;Before the plate is 5 mm thick transparent acrylic board, board for UV printing after 5 mm thick white acrylic plate;37 mm plate before and after 6 available process screw fixed on the wall;The back is equipped with dust cover.When aluminum ring from upper free fall, one by one through the magnet, acrylic tube to produce induced current in the aluminum ring, and the magnetic field produced by induced current magnet instead, forcing aluminum ring down slowly.
