if the magnetic field produced by the magnets in a generator is constant, does the magnetic flux through the generator coil change when it is turning? Explain.
Magnetic flux through the coil is given by B.A, which is given by BAcos(theta), where theta is the angle between area vector(direction of area vector is perpendicular to the plane of coil) and the magnetic field. So when the generator coil is turning, although the magnetic field and area of the coil is not changing, angle between the magnetic field vector and area vector is changing, Due to which flux through the coil is changing, which in turn induce a emf in the coil.
