(c) What are the sources of, on the one hand, an electric field, and on the other, a magnetic field? (e) What does Lenz's law say, and where is it in Maxwell's equations? (f) Can there be an emf (potential difference) induced in a circuit at an instant when the magnetic flux through the circuit is zero?
