Choose the correct statement
1 The magnetic field due to current carrying conductor lie in a plane parallel to the conductor.
2 The magnetic field due to current carrying conductor is uniform in a plane perpendicular to the conductor.
3 The magnetic field due to current carrying conductor is non uniform in a plane perpendicular to the conductor.
4 The magnetic field due to current carrying conductor is zero in a plane perpendicular to the conductor.

Two parallel infinitely long current carrying wires are shown in the figure. If resultant magnetic field at point \(A\) is zero, then determine the value of current \(I\).
1 \(50\,A\)
2 \(15\,A\)
3 \(30\,A\)
4 \(25\,A\)
Explanation:
Resultant magnetic field due to current carrying parallel wire \(1(10 A)\) and wire \(2(I A)\) at point \(A\) is zero. i.e. \(B_{1}=B_{2}\) \(\dfrac{\mu_{0} I_{1}}{2 r_{1}}=\dfrac{\mu_{0} I_{2}}{2 r_{2}} \quad \Rightarrow \dfrac{I_{1}}{r_{1}}=\dfrac{I_{2}}{r_{2}}\) \(\Rightarrow \dfrac{10}{9 \times 10^{-2}}=\dfrac{I}{27 \times 10^{-2}}\) \(\Rightarrow I=30 A\) So, correct option is (3)
