Open Question: Faraday and Lenz's Law Problem?
Assume that there is a steady current I flowing in the coil it is clockwise as seen from above the coil. While there is a steady current in the coil induced current in the metal ring suspended at the top of the coil will be in the _____________ direction as seen from above the coil. If the current is reduced from its steady value to zero, while it is changing the induced current in the metal ring will be in the _______________ as seen from above the coil.
