冷次定律示範器 Lenz's Law Demonstrator
產品型號: MG-8600
廠牌名稱: PASCO Scientific
As the magnet falls, it generates a current in the walls of the tube, moving in one direction above the magnet and in the opposite direction below the magnet. Both currents obey Lenz’s Law and induce magnetic fields that oppose the motion of the magnet.
