This chapter answers the question the last two left open: if currents make magnetic fields, can magnetic fields make currents? Faraday and Henry showed that they can, but only when the magnetic flux through a circuit changes. The chapter defines flux, states Faraday's law and Lenz's law, derives motional emf from both flux change and the Lorentz force, introduces mutual and self-inductance with the energy an inductor stores, and ends with the ac generator.
