A current circular loop of radius R is placed in the x-y plane with centre at the origin. Half of the lop 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
