Magnetic Force on segment of wire

  1. Mar 5, 2004 #1
    A segment of wire carries a current of 30 A along the x-axis from x=-6m to x=0 and then along the z axis from z=0 to z=5.5m. In this region of space, the magnetic field is equal to 14mT in the positive z direction. What is the magnitude F of the force on the segment of wire? Answer in units of N.

    I'm not sure what formula to use, can anyone help?

    The magnetic force on a segment of current-carrying wire is:
    [tex]F = i\vec{l} \times \vec{B}[/tex]
