Two identical long conducting wires AOB and COD are placed at right angle to each other, will one above other such that O is their common point for the two. The wires carry I₁ and I₂ currents respectively. Point P is lying at distance d form O along a direction perpendicular to the plane containing the wires. The magnetic field at the point P will be
Options
(a) (μ₀/2πd) (I₁/I₂)
(b) (μ₀/2πd) (I₁+I₂)
(c) (μ₀/2πd) (I₁²-I₂²)
