Two parallel conductor rails with negligible resistance are connected at one end by a resistance resistor R=1.40 Ω, as shown in the figure. The rails are placed in an upwardly directed magnetic field B= 5.00 T , which is perpendicular to the plane of the rails. This magnetic field is uniform and independent of time. The distance between the rails is l= 0.20 m. A conductor bar slides without friction on the top of the two rails at a constant...
