The armature of a small generator consists of a flat, square coil with N turns and sides with length L. The coil rotates in a magnetic field of magnitude B with a constant angular speed ω.   Write an expression for the flux ΦB(t) through the coil as a function of time. Assume the plane of the coil is perpendicular to the magnetic field at time t=0. Your answer should be in terms of ω, N, B and L.
