Hello,

I can calculate the correct value for the problem. However, I do not understand why the torque is at -y direction. I tried using the right-hand rule but still no avail. Maybe I was applying this rule incorrectly. Could you please help me explain explicitly on how to determine the direction of the torque on this problem via the right-hand rule?

Figure 28-45 shows a rec-
tangular 20-turn coil of wire, of di-
mensions 10 cm by 5.0 cm. It carries
a current of 0.10 A and is hinged
along one long side. It is mounted in
the xy plane, at angle 0 = 30° to the
direction of a uniform magnetic field
of magnitude 0.50 T. In unit-vector
notation, what is the torque acting
on the coil about the hinge line?
