Tossup

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 (10[1])slowly. This process is governed (10[1])by the equation “del cross E equals minus dB/dt,” (10[1])which implies that the negative time derivative of magnetic flux equals (-5[1])the emf (10[1])(“E-M-F”). This process creates eddy currents that rapidly (10[1])heat metal in a namesake type of cooktop. (10[1])Lenz’s (10[1])Law (10[1])explains (10[2])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■ (10[1])
