(b) The textbook, in §32-7, makes it clear that µ is in the same direction as
B, and the effect of
Fis
to move the material towards regions of larger |
B|values. The direction of the magnetic moment
vector (of our loop) is toward the right in our sketch.
(c) See our comments in part (b). Since the size of |
B|relates to the “crowdedness” of the field lines,
we see that
Fis towards the left in our sketch.
