Calculating Current and Torque in a Rectangular Loop

[matt72lsu]

Homework Statement

A rectangular loop of 260 turns is 33 cm wide and 17 cm high.
What is the current in this loop if the maximum torque in a field of 0.49 T is 24 N m?

Homework Equations

torque (t) = NIABsintheta

The Attempt at a Solution

I'm not actually sure if this is even the correct equation. It was the closest one I could find with most of the variables. If it is the correct one, how do you find sin? Thanks for the help

The torque is maximum when theta is pi/2.

i have no idea what that means

i have no idea what that means

The torque is maximum when theta is pi/2. So that sin(pi/2) = 1.
