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 forceon the charge qin the rod is rrrFqvBB=×. 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=⋅=×⋅=∫∫1qFdlvBdlvLBBrrrrr. In Steady State: In steady state a charge qin the rod
