Homework Help: Magnitude of the electric field

  1. Feb 23, 2010 #1
    Problem:
    The moving rod is 10cm long and is moving at a speed of 15cm/s. If the magnetic field is.8T calculate the magnitude of the electric field in the rod

    There is a picture with a rod and the velocity perpendicular to the length of the rod

    Equation:
    Emf=vBL

    My attempt:
    I converted cm to m
    (.1m)(.15m/s)(.8T)
    Emf: .012 V/m

    When i submitted my value it was wrong, help would be greatly welcomed
