Homework Help: How to determine the potential difference?

  1. Jan 15, 2010 #1
    1. A horizontal rod(oriented in e-w direction) is moved northward at constant velocity through a magnetic field that points straight down.

    2. Why is the west end of the rod is at higher potential than the east end?

    3. I have no idea how to obtain any information about V.

    Show us the equation for the Lorentz force. How can you use it to help you answer this question?
