Magnetic Induction and Lenz's Law Kit

£ 31.95
This high quality, low cost kit is ideal for demonstrating magnetic induction and Lenz's Law. The kit includes a coil, magnet, light emitting diode (LED), copper tube and metal slug. Movement of the magnet through the coil induces a current and lights the LED. The magnet dropped through the copper tube falls more slowly than when outside the tube and when compared to the non-magnetic slug.Lenz's Law: In 1834, Heinrich Lenz postulated the following law; "An induced current is always in such a direction as to oppose the motion or change causing it".
