David Griffiths claims that there are really two laws of this process and that only relativity explains the equivalence between a central quantity and its “motional” form. In a common demonstration of this process, a magnet dropped through a copper tube falls unexpectedly slowly. This process is governed by the equation “del cross E equals minus dB/dt,” which implies that the negative time derivative of magnetic flux equals the emf (“E-M-F”). This process creates eddy currents that rapidly heat metal in a namesake type of cooktop. Lenz’s Law explains the negative sign in Faraday’s law of this process. For 10 points, name this process in which a changing magnetic field creates an electric field. ■END■
