1. The problem statement, all variables and given/known data In the ATTACHMENT is the given circuit. Which contains two resistance R1 and R2 in form of circle of radius r = 1 m with a battery having e.m.f. V = 10∏ volt. Upper resistance is having resistivity = 4Ω-m & lower resistance having resistivity = 2Ω-m. Angle between two points A and B is 60°. (wires have same cross section A1 = A2 = 2 cm2) Find magnitude of magnetic field at centre. The attempt at a solution I tried it using the formula B = μiθ/4∏r. BUT THE ANSWER IS NOT COMING CORRECT.
