Is the magnetic field inside the loop increasing in strength, decreasing in strength, or steady?
Background: There is a counterclockwise induced current in the conducting loop shown in the figure.
Question: Is the magnetic field inside the loop increasing in strength, decreasing in strength, or remaining steady?
Possible Answers: 1. Increasing in strength 2. Decreasing in strength 3. Remaining steady
I suspect that the magnetic field is increasing in strength, but I'm not entirely sure. Could you provide any pointers or 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.
