A wire lying along the x-axis carries a current of 5.5 A

    1. The problem statement, all variables and given/known data

    A wire lying along the x-axis carries a current of 5.5 A in the positive x-direction. It lies in a nonuniform magnetic field, given by B = (2.0 T/m2)x2i + (2.0 T/m2)x2j, with the magnetic field in Tesla and x in meters. (a) If, from your view, the positive x-direction is to the right and the positive y-direction is up, what is the direction of the net force on a section of wire between x = 0 and x = 2.0 meters? (b) What is the magnitude of the magnetic force on the section of wire between x = 0 and x = 2.0 meters?

    2. Relevant equations

    F=IL X B
    F=ILBsin(theta)

    3. The attempt at a solution
    I have plugged in the values given and I am pretty sure that the direction of the force is "towards you" (the options are towards you and away from you). I have gotten some values which I think are too big (ie 16 T for the magnetic field).
