In a physics laboratory experiment a coil having 200 turns enclosing an area of 12.0cm^2 is rotated from a position where its plane is perpendicular to earth magnetic field to one where its plane is parallel to the field . The reason takes 4.00*10^-2s the earth’s magnetic field at the laboratory is around 6.00*10^-5 T. Determine the magnetic flux via the coil before it is rotated. Determine the net magnetic flux via the coil after it is rotated?
