A conducting loop lies in the plane of the page and carries

A conducting loop lies in the plane of the page and carries a counterclockwise induced current. Based on this evidence, which of the following statements could be true? A constant magnetic field points into the page. A constant magnetic field points out of the page. A decreasing magnetic field points into the page. A decreasing magnetic field points out of the page. An increasing magnetic field points into the page. An increasing magnetic field points out of the page. Explain your response in the space provided.

Solution

if the current induced is clockwise , then the B due to the induced current points into the page, This B is trying to prevent the reason of its creation... from Lenz\'s law. That means , there was a magnetic field in upward direction that is increasing... or... there was a magnetic field in downward direction whict is decreasing.

so, C and F are the correct options
