What Orientation Produces Maximum Torque in a Magnetic Field?

[Inertialforce]

Homework Statement

The problem is as seen in the attachment.

Homework Equations

T(torque) = (N)(I)(A)(B)(Sin(theta))

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.

\theta 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 \theta 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?
