1. The problem statement, all variables and given/known data Two circular loops of wire, each containing a single turn, have the same radius of 3.6 cm and a common center. The planes of the loops are perpendicular. Each carries a current of 2.0 A. What is the magnitude of the net magnetic field at the common center? I have been using this equation: B = uI/2(3.14)r Where u = 4(3.14) x 10^-7, I= 2.0 Amperes, and r = .036 meters. When I work through the equation this way, I end up with: B = 1.111 x 10^-5 It tells me that this answer is wrong and I only have one more attempt at this problem. thanks.
