What is the direction of the resulting force on this current

  1. Mar 7, 2016 #1
    1. The problem statement, all variables and given/known data
    A vertical wire carries a current straight up in a region where the magnetic field vector points due north. What is the direction of the resulting force on this current?

    The diagram shows a force arrow perpendicular to the B (magnetic field arrow). The magnetic field is pointing out of the page.
    2. Relevant equations

    Fingers - pt I
    Palm - magnetic field
    Thumb- direction of force
    3. The attempt at a solution
    When I place my thumb in the direction of the arrow marked "F", it goes to the left (west) but I am having trouble lining every component of the RHR up.
