Question
Correct Answers: The current induced in the rod is 2.5A, and the magnitude of the force is required to keep the rod moving at a constant speed is 0.89N. The direction of this force is to the left.
I don't understand why the direction of the force is to the left. Using the right hand rule i thought the force moved downward?
Constants The figure shows a 25-cm-long metal rod pulled along two frictionless, conducting rails at a constant speed of 4.0 m/s. The rails have negligible resistance, but the rod has a resistance of 0.55 ? .(Figure 1) Figure 1 of1 ????? B= 1.4T ?????Explanation / Answer
What you found using right hand rule is force on + charge moving to leftward. So lower end of road will be charged + (higher potential)
force on road which have downward current will be towards right . so we need to apply force leftward to move road with constant velocity
