A current carrying circular loop of radius R is placed in the x-y plane with centre at the origin. Half of the loop with x > 0 is now bent so that it now lies in the y-z plane.
A. The magnitude of magnetic moment now diminishes
B. The magnetic moment does not change
C. The magnitude of B at (0, 0, z), z > R increases
D. The magnitude of B at (0, 0, z), z >> R is unchanged
