Question : The given figure shows a right-angled isosceles Δ PQR having its base equal to a. A current of I ampere is passing downwards along a thin straight wire cutting the plane of paper normally as shown at Q. Likewise a similar wire carries an equal current passing normally upwards at R. Find the magnitude of the magnetic field induction B at P. Assume the wires to be infinitely long.
