After evaluating the force on each current segment, find the net torque exerted about the
axis of rotation (which is where?) by direct evalution of **r** x **F** for each segment.

Calculate the magnetic dipole moment of this triangular current loop and evaluate the torque
from **mu** x **B**. Compare to previous answer!
