Faraday's Law: Rotating Ring Description

Faraday's Law: Rotating Ring illustrates the electromagnetic interaction between a conducting non-magnetic ring and constant external magnetic field. Adjusting the ring's radius and rotation, or the magnitude of the external field, causes the magnetic flux through the ring to change. This change gives rise to a current in the ring which is in a direction such as to oppose the change in flux, as described by Lenz's Law. If the resistance of the ring is zero, the change in induced flux in the ring will exactly counter the change in external flux due to the external field, thus keeping the total flux constant. Increasing the resistance hinders the flow of induced current, resulting in a delay in the response of the ring to the change in external flux, and a corresponding change in total flux. This can be seen in the flux graph as you manipulate the parameters. Get the Faraday's Law: Rotating Ring application and give it a try to fully assess its capabilities!
