The Lenz's Law Kit provides the necessary tools to discover concepts involving Farady's Law magnetism and eddy currents in addition to the Lenz's Law. The pipes of differing materials excel at demonstration the magnet braking force in action as the two magnets are simultaneously dropped through each of the aluminum and clear plastic tubes. A dynamometer attaches to suspend the Lenz's Las apparatus so students can quantitatively measure the additional force as the magnet drops through the conductive tube.Supplied with instructions.
