A loop of wire has the shape shown in the drawing. The top part of the wire is bent into a semicircle of radius r = 0.20 m. The normal to the plane of the loop is parallel to a constant magnetic field (theta = 0 degree) of magnitude 0.75 T. What is the change in the magnetic flux ( delta phi) that passes through the loop when, starting with the position shown in the drawing, the semicircle is rotated through half a revolution?
