You hold a wire coil so that the plane of the coil is perpendicular to a magnetic field vector B. Vector Bis kept constant but the coil is rotated so that the magnetic field, vector B , is now in the plane of the coil. How will the magnetic flux through the coil change as the rotation occurs? Check all that apply. The flux is unchanged because the magnitude of vector B is constant. The flux increases because the angle...
