A wire in Figure the shape of a semicircle with radius a is oriented in the yz-plane with its center or curvature at the origin If the current in the wire is I. calculate the magnetic-field components produced at point P, a distance x out along the x-axis. (Note: do not forget contribution from the straight wire at the bottom of the semicircle that runs from z = −a to z = +a. you may use the fact that the fields of the two anti parallel currents at z > a cancel, but you must explain why they cancelled?
