Lenz’s law, named after the physicist Emil Lenz who formulated it in 1834, states that the direction of the current induced in a conductor by a changing magnetic field is such that the magnetic field created by the induced current opposes the initial changing magnetic field.

Demonstrate this law by dropping a magnetised object down a tube, timing and comparing with the same unmagnetised object dropped down the same tube.
