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?
