Find the flux of the Earths magnetic field of magnitude 5.00 10-5 T through a square loop of area 30.0 cm2 (a) when the field is perpendicular to the plane of the loop, (b) when the field makes a 50.0 angle with the normal to the plane of the loop, and (c) when the field makes a 90.0 angle with the normal to the plane.
