Question
Consider the long, straight, current-carrying wires shown in the figure. One wire carries a current of 6.5 A in the positive y direction; the other wire carries a current of 4.5 A in the positive x direction.
Calculate the magnitude of the net magnetic field at points A and B.

B = mu I / 2 pi r
mu = 4 pi * 10-7 Tm/A
BA = [mu I1 / 2 pi r1] + [mu I2 / 2 pi r2]
= [mu * 4.5 / 2 pi (0.16)] + [mu * 6.5 / 2 pi (0.16)]
BA = 1.375 * 10-5 T
--------------------------------------------------
BB = [mu I1 / 2 pi r1] - [mu I2 / 2 pi r2]
= [mu * 4.5 / 2 pi (0.16)] - [mu * 6.5 / 2 pi (0.16)]
BB = -2.5 * 10-6 T
