A conducting rod whose length is 25 cm is placed on a U-shaped metal wire that has a resistance of 8 ohm. The wire and rod are placed in the plane of the paper. A constant magnetic field of strength 0.40 T is applied out of the paper. An applied force 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 the wire?
Fwire = iLB
I = V/R
F = qvB
The Attempt at a Solution
I don't understand how to solve for the current. Is there a relationship between velocity and something else here that can help me solve for it? I have the length (.25m) and B field (.40T), so if I knew current I could solve for F. I also don't know how to find q of the conducting rod.
The figure is attached. Thanks!
