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...
