magnetic field ?? 1. The problem statement, all variables and given/known data A single loop of wire of radius 3 cm carries a current of 2.4 A. What is the magnitude of B on the axis of the loop at the following position? 1 cm from the center 2. Relevant equations Uo/4(pi) * (2(pi)R^2 *I) / (z^2 + R^2)^(3/2) where Uo is 4(pi) X 10^-7 3. The attempt at a solution i just pluged in values R = .03 m z = .01 m I = 2.4 A i got 4.2357797e-4 T but that is wrong?? does anyone see something that im doing wrong? any help would be great!!
