Is the magnetic field inside the loop increasing in strength?

Decreasing

Explanation:

The figure of the problem is missing: find it in attachment.

The phenomenon of electromagnetic induction occurs when there is a change in magnetic flux through a coil; when this happens, an electromotive force is induced in the coil, according to Faraday-Newmann-Lenz Law:

where

is the rate of change of the magnetic flux

The negative sign indicates the direction of the induced emf, which is such that it opposes the change in the magnetic flux.

In this problem, we are told that there is a counterclockwise current induced in the conducting loop: this is a result of the phenomenon of electromagnetic induction.

This current will therefore produce an additional magnetic field. We can use the right-hand rule to determine the direction of the induced magnetic field: the thumb is placed in the direction of the current, the other fingers wrapped around the thumb gives the direction of the field. If we apply this rule to this situation, we see that the direction of the magnetic field inside the loop is out of the page. This is opposite to the direction of the external magnetic field, which is inside the page: therefore, the magnetic field inside the loop is decreasing in strength, since the two field have opposite directions.

what is the actual question though?
