In Figure 29.1, charge accumulates at the ends of the moving rod until the amount at each end reaches an equilibrium value. Mechanical equilibrium is established when the magnetic force due to the motion of the rod counterbalances the electric force due to the charge separation. In Figure 29.10, what two forces determine the equilibrium state of the charge separation in the stationary rod?

Figure 29.1 When a conducting rod moves in a magnetic field, positive charge carriers in the rod experience a magnetic force. In the configuration shown, the right-hand force rule tells us that a positive charge accumulates at the bottom of the rod. B out of page right-hand force rule: . conducting rod The direction of magnetic force on charge carriers Force causes + charge to accumulate at this end.
