FIGURE 29-12 -A Conducting Rod Whose Length Is 25 Cm Is Placed

question 83

Short Answer

FIGURE 29-12
-A conducting rod whose length is 25 cm is placed on a U-shaped metal wire that has a resistance R of 8 Ω as shown in Fig. 29-12. The wire and the rod are in the plane of the paper. A constant magnetic field of strength 0.4 T is applied perpendicular and into the paper. An applied force moves the rod to the right with a constant speed of 6 m/s.
(a) What is the magnitude of the induced emf in the wire?
(b) What is the magnitude and direction of the induced current in the wire?
