PHY2061 R. D. Field Department of Physics chp34_1.doc University of Florida Electromagnetic Induction Conducting Rod Moving through a Uniform Magnetic Field: The magnetic force on the charge q in the rod is r r r Fq v B B . The induced EMF, ε , is equal to the amount of work done by the magnetic field in moving a unit charge across the rod , ε =⋅ = × = ∫∫ 1 q Fd l v B d l v L B B r r r r r . In Steady State: In steady state a charge q in the rod
