Question

Two straight long conductors AOB and COD are
perpendicular to each other and carry currents I₁ and I₂.
The magnitude of the magnetic induction at a point P at a
distance a from the point O in a direction perpendicular to
the plane ABCD is
(a) μ₀/2πa (I₁ + I₂ )
(b) μ₀/2πa (I₁ - I₂ )
(c) μ₀/2πa (I₁² - I₂² )¹/²
(d) μ₀/2πa I₁I₂/I₁² - I₂²
