In the diagram at right, an uncharged conducting bar is moving with constant velocity v to the left through a region where there is a uniform magnetic field pointing out of the page. What charge distribution will the bar have, as a result of its motion? B out of page The bottom of the bar will have positive charge, and the top of the bar will have negative charge. The bar will remain electrically neutral at all points. The top of the bar will have positive charge, and the bottom of the bar will have negative charge. The right side of the bar will have positive charge, and the left side of the bar will have negative charge. The bar will gain a net positive charge, distributed uniformly along its length. The bar will gain a net negative charge, distributed uniformly along its length, The left side of the bar will have positive charge, and the right side of the bar will have negative charge.
