Question

Two identical long conducting wires A O B and C O D are placed at right angle to each other, with one above other such that ‘ O ’ is their common point for the two. The wires carry I 1 and I 2 currents, respectively. Point ‘ I ’ is lying at distance ‘ d ’ from ‘ O ’ along a direction perpendicular to the plane containing the wires. The magnetic field at the point ‘ P ’ will be:, μ 0 2 π d I 1 I 2, μ 0 2 π d I 1 + I 2, μ 0 2 π d I 1 2 - I 2 2, μ 0 2 π d I 1 2 + I 2 2 1 / 2
