Question

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 speed v= 2.00 m/s . Use Faraday's law of induction to calculate the induced current in the busbar.

Answer #1

Emf induced in the rod, E = Blo - 5.080,20x210 & = 2.0 volt R = 1.402 onduced currents in bar, 1 = 6.4285 Amp I = 1.43 amp.
