An infinetily long conductor PQR is bent to form a right angle. A current of I passes through PQR . The magnetic field at ponit M which is above Q at a didtance d is B 1 . Now another infinitely long straight conductor QS i connected to Q so that the current is (½)I in both QR and QS ,the current in PQ remaining unchanged. the magnetic field at M is now B 2 . Then find the ratio of B 1 and B 2.
