Electromagnetic pumps

  1. Apr 22, 2010 #1
    "Electromagnetic pumping is a non-invasive method of moving liquid used in situations where the moving parts of traditional pump are not practical. Pumping liquid metal is an example. Electromagnetic pumping involves applying an electric field and a magnetic field at the same time. Consider a pipe oriented perpendicular to the screen, a magnetic field applied from left to right, and an electric field directed upward. Determine the direction of the force on an ion in the liquid. Does the direction of the force depend on the charge of the particle?"

    Don't even know where to start with this one. Looked and looked for appropriate formulae but the only one I could find was F = IL + B. Is this right? If so, what does the L stand for?
