Interaction of a Current Loop with a Magnetic Field

[HELLO11]

Homework Statement

Assume that the current flowing into the loop is 0.500A . If the magnitude of the magnetic field is 0.300 T, what is torque , the net torque about the vertical axis of the current loop due to the interaction of the current with the magnetic field?

the loop is initially positioned at (theta)=30 degrees

Please provide the complete statement of the problem exactly as it was given. (A diagram would be helpful; lacking that, describe the direction of magnetic field compared to the orientation of the current loop.)
