Homework Help: Torque and magnetic fields

  1. Jan 14, 2009 #1
    1. The problem statement, all variables and given/known data
    The problem is as seen in the attachment.

    2. Relevant equations
    T(torque) = (N)(I)(A)(B)(Sin(theta))

    3. The attempt at a solution
    For this question I used the above formula to find the magnitude of the torque, but what I am not sure about is which orientation would produce the "maximum torque" that it is asking about.

    Could someone please tell me which orientation would give a "maximum torque" and why?

    By the way, I calculated the magnitude of the torque to be 18 Newton*meters.

    [tex]\theta [/tex] is the angle between the coil and the the direction of magnetic induction. or rather the direction of the current and the magnetic induction. Now try putting the values of [tex]\theta[/tex] accordingly and try and get the answer. By the way, what did you take the value theta to be, when you calculated its magnitude as 18Nm?
