Homework Help: Comparing Current, Force, B Field, Magnetism

  1. Oct 9, 2012 #1
    1. The problem statement, all variables and given/known data

    Please see the attachment and see where i went wrong... simple T/F questions

    2. Relevant equations

    3. The attempt at a solution

    Here's what i tried

    1. T (Right hand rule for both I1 and I2 where I2=-I1
    2. F (Since I2 has no current, there is no B field from I2 so the B field is from the right hand rule of I1 making the field point down)
    3. T There is no force on the particle if there is no velocity
    4. T (force is perp to the b Field and since the B field point s down, force must be into the page
    5. F again force should be into the page
    6. T b field from I2 is out of the page so th froce is perpendicular making it point down
    7. T Opposite force directions should make the lines repel?
