Two straight parallel conductors are spaced \( 50 \mathrm{~cm} \) apart and carry oppositely directed currents, the first \( 20 \mathrm{~A} \), the second 24A. A point \( P \) is separated from the first conductor by a distance of \( 40 \mathrm{~cm} \) and from the second by \( 30 \mathrm{~cm} \). Calculate the magnetic field of induction at \( P \).
