An infinitely long conductor PQR is bent to form a right angle as shown A current I flows through PQR The magnetic field due to this current at the point M is H Now another infinitely long straight conductor QS is connected at Q so that the current in PQ remaining unchanged The magnetic field at M is now H The ratio H H is given by IM 90 90 IR
