In a physics laboratory experiment, a coil with 190 turns. Each turn of the coil encloses an area of 7.0 cm2. The coil is rotated from a position where its plane is perpendicular to the earth's magnetic field to one where its plane is parallel to the field. The rotation takes 5.0 x 10-2 s. The earth's magnetic field at the location of the laboratory is 6.0 x 10-5 T.
Part A: Obtain the magnetic flux through one turn of the coil before it is rotated?
Part B: Find the average emf induced in the coil as it is rotated from the perpendicular to the parallel orientation?
