A rod of m= 1.5 kg rests on two parallel rails that are L = 0.85 m apart. The rod carries a current going between the rails (bottom to top in the figure, into the page) with a magnitude I = 2.7 A. A uniform magnetic field of magnitude B= 0.85 T pointing upward is applied to the region, as shown in the figure. The rod moves a distance d = 0.15 m along the rails in a given time period. Ignore the friction on the rails. L Express the magnitude of the magnetic force F on the rod, in terms of the length L, current I, and magnetic field B. Calculate the numerical value of F, in newtons. Which direction does the rod move? 100
