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 placed along a diameter of the coil.
(a) Evaluate 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, evaluate the net flux through the coil.
