Jumping Ring Experiment
Experiment: A coil is wound around an iron core which is held
vertically upright. A metallic ring is placed on top of the iron core. A current is then switched on to pass through the coil. This will make the ring jump several meters
Explanation:
Before the current in the coil is turned on, the magnetic flux through the ring is zero. Afterwards, the flux appears in the coil in upward direction. This change in flux causes an induced emf and induced current as well in the ring. The direction of induced current in the ring will be opposite to the direction of current in the coil, as
dictated by Lenz’s law. As the opposite currents repel, the ring flies off in air.
