Suppose you have a long straight wire AB, carrying a current in the direction shown in the figure. Below this wire is a rectangular loop 20 cm long and 5 cm wide, carrying a current of equal magnitude to the wire, where the long sides are parallel to the wire.

Two coils that are separated by a distance equal to their radius and that carry equal currents such that their axial fields add are called Helmholtz coils. A feature of Helmholtz coils is that the resultant magnetic field between the coils is very uniform. Let R = 11.0 cm, I = 23.0 A, and N = 300 turns for each coil. Place one coil in the y-z plane with its center at the origin and the other in a parallel plane at R = 11.0 cm. Calculate the resultant field Bx at x1 = 2.8 cm, x2 = 5.5 cm, x3 = 7.3 cm, and x4= 11.0 cm.
