A long straight wire lies in the plane of a circular coil with a radius of 0.020 meter. The wire carries a current of 5.0 Amp and is located along a diameter of the coil.
(a) Determine what is the net flux through the coil?
(b) If the wire passes through the center of the coil and is perpendicular to the plane of the coil, find what is the net flux through the coil.
