Force due to B on a current carrying conductor

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

    a thin straight wire of length 0.4m is suspended from a spring balance. the scale reads 2g. the horizontal component of the earth's magnetic field at that place is Bh=3*(10^-5)T. the wire is held horizontal and at right angles to Bh.if a current of 500A is passed through the wire determine the two possible readings on the scale.

    2. Relevant equations


    3. The attempt at a solution
    F=BIL=3*(10^-5)*0.4*500=0.006N. this should be ok?
    0.02+0.006=0.026N..i am not sure after this...
