1. Taking the B-wave to be sinusoidal, derive the expression for flux/pole.
2. Write the expression for flux linkages of an N-turn coil if the B-wave is sinusoidal and rotating at synchronous speed w rad/s.
3. Draw the phasor diagram relating emf phasor to flux phasor.
4. Sketch the mmf wave of an N-turn coil carrying current i. Write the expression for its fundamental if i is sinusoidal. What kind of wave is this?
