When current is flowing through the coil, the direction of the torque can be thought of in two ways. Either as the
result of the forces on current carrying wires, or as a magnetic dipole moment trying to line up with an external
field (e.g. like a compass). Note: the magnetic moment of a coil points in the direction of the coil's magnetic
field at the center of the coil.
d) Forces: We can consider the left-most piece of the loop (labeled ○) as a short segment of straight wire
carrying current directly out of the page at us. Similarly, we can consider the right-most piece of the loop
(labeled ) as a short segment straight wire carrying current directly into the page, away from us. Add to
the picture below the two forces due to the external magnetic field acting on these two segments. Then
describe how these two forces give a torque and determine if the torque acts to rotate the loop clockwise or
counterclockwise according to this picture?
