Homework Help: Strength of magnetic field F = ILBsin(theta)

  1. Jun 16, 2009 #1
    1. The problem statement, all variables and given/known data

    How many times stronger is the force acting on the conductor at 90 degrees than it is at 30 degrees?

    2. Relevant equations
    F = ILBsin(theta)

    3. The attempt at a solution

    I would think the answer is two times as strong because sin90 = 1 and sin30 = 0.5.
    But the question is worth 5 marks so I think there must be something more to it..
