Two straight parallel conductors are `50cm` apart and carry oppositively directed currents, held perpendicular to the plane of paper as shown in figure. The current in first conductor, `I_1=20A` and in the second conductor is `I_2=24A`. A point P is separated from the first conductor by a distance of `40cm` and the second conductor by `30cm`. Calculate the magnetic field at point P.

Answer

`[188.68xx10^(-7)T and alpha-32^(@)]`
