Ring Falling in a Magnetic Field

Three aluminium objects are dropped through a magnetic field. The objects move slower entering and leaving the field due to changes in the flux through the object. The change in the flux through a conductor results in a force which opposes additional flux change. As a result the force opposes the motion and slows the object's fall. This demonstration illustrates Faraday's and Lenz's law.
