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.

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
