Question

The plane of a conducting wire loop is oriented parallel to the x-y plane. A magnetic field is directed in the z-direction. Which action will NOT change the magnetic flux through the loop?
Options
A Decrease the area of the loop
B Increase the strength of the magnetic field
C Rotate the loop about an axis in the z-direction through its centre
Correct Answer
D Rotate the loop about an axis in the y-direction through its centre
Correct Answer

Option C is the correct answer.

Detailed Explanation

Spinning the loop about the z-axis - the axis ALONG the field - leaves the loop lying flat in the same plane, so A, B and theta are all unchanged and the flux stays the same.
