Question

The diagram shows a region of space containing an electric field. The electric field is represented by the arrows shown in the diagram, where each arrow shows the strength (according to the arrow's length) and direction of the electric field at the point from which the arrow emerges.
Which of the following could explain what is happening in this region of space?

• A. A magnetic field directed into the page is constant in time.
• B. A magnetic field directed out of the page is constant in time.
• C. A magnetic field directed into the page is increasing with time.
• D. A magnetic field directed out of the page is increasing with time.
• E. A magnetic field directed out of the page is decreasing with time.

Answer 1

The correct option is D A magnetic field directed out of the page is increasing with time.

In the given diagram shows the electric field due to circular ring segment the magnetic field due to this loop is directed into the page if means two case possible. (i) Either magnetic field into the page and decreasing or (ii) Magnetic field directed out of the page and increasing. Only option D correct.
