A long, straight wire lies in the plane of a circular coil with a radius of 0.040 m. The wire carries a current of 5.0 A and is placed along a diameter of the coil.
(a) 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 the net flux through the coil.
