Question

 Two wires AO and OC carry equal currents i as shown in Fig. One end of both the wires extends to infinity. Angle AOC is α. The magnitude of magnetic field is point P on the bisector of these two wires at a distance r from point O is

• A. \(\frac{μ_0}{2πr}\frac{i}{r}cot\frac{α}{2}\)
• B. \(\frac{μ_0}{4πr}\frac{i}{r}cot\frac{α}{2}\)
• C. \(\frac{μ_0}{2π}\frac{i}{r}\frac{1+cos(\frac{α}{2})}{sin\frac{α}{2}}\)
• D. \(\frac{μ_0}{4πr}\frac{i}{r}\frac{α}{2}\)

Answer 1

The Correct Option is C

The correct answer is option C) \(\frac{μ_0}{2π}\frac{i}{r}\frac{1+cos(\frac{α}{2})}{sin\frac{α}{2}}\)
