Question
•29 In Fig. 30-52, a metal rod is
forced to move with constant veloc- T
ity v along two parallel metal rails, i
connected with a strip of metal at
one end. A magnetic field of magni-
tude B = 0.350 T points out of the
page. (a) If the rails are separated
by L = 25.0 cm and the speed of the
rod is 55.0 cm/s, what emf is gener-
ated? (b) If the rod has a resistance of 18.0 N and the rails and con-
nector have negligible resistance, what is the current in the rod?
(c) At what rate is energy being transferred to thermal energy?
