Unformatted text preview: In the figure below, the rod moves to the right with a speed of 1.6 mfs, and has a resistance of 2.2 Q. The rail separation is E = 25 cm. The magnetic field is 0.37 T, and the resistance
of the U-shaped conductor is 26.0 Q at a given instant. (a) Calculate the induced emf. -~Iv (l3) Calculate the current flowing in the U—shaoed conductor. _.».. (c) Calculate the external force needed to keep the rods .velocity constant at that instant. -"N ...
