A conducting rod whoselength is 25 cm is placed on a U-shaped metal wire that has aresistance of 8.0 as shown in Figure 23-10. The wire andthe rod are placed in the plane of the paper. A constant magneticfield of strength 0.40 T is applied out of the paper. An appliedforce moves the rod to the left with a constant speed of 6.0 m/s.What is the magnitude and direction of the induced current in thewire? 75 mAclockwise 75 mAcounterclockwise 17 mAclockwise 52 mAclockwise 17 mAcounterclockwise

Explanation / Answer

The induced current in the wire is      I = Blv/R          =(0.40T)(25*10-2m)(6.0m/s) /8.0            =75mA according to lenz's law ,this current must be clockwise.
