Is the magnetic field inside the loop increasing in strength, decreasing in strength, or steady?

Question

Background:There is a counterclockwise induced current in the conducting loop shown in the figure. See image: http://session.masteringphysics.com/problemAsset/1...Question: Is the magnetic field inside the loop increasing in strength, decreasing in strength, or steady? Possible Answers:increase in strengthdecrease in strengthremaining steady I have a feeling that there would be an increase in strength, but I'm not 100% sure. Any pointers/suggestions??

The current should be the other way for a right handed coordinate system. There is an induced current so the magnetic field must be changing; by Lenz's Law, the induced magnetic field must be created from the induced current such that the induced magnetic field opposed the change in flux. In this figure, the change in flux is upwards, or into the page, so the magnetic field is losing strength, and there is an induced magnetic field opposite the direction of the change in flux which produces the current.
