A flat, rigid circular loop of radius \(R\) carries a steady current \(I\) in the counterclockwise direction when viewed from above the \(xy\)-plane. The loop lies entirely in the \(xy\)-plane, centered at the origin. A uniform magnetic field \(\vec{B} = B_0 \hat{i} + 2B_0 \hat{j} - 3B_0 \hat{k}\) is present throughout the region. What is the magnitude of the net magnetic torque exerted on the loop?
