Hint 1: this problem is
different from problem A
because the magnetic
field now has a vertical
component!
Hint 2: this section is
easier if you think of
the charge-carriers in
the loop as positive!
Hint 3: "magnetic
moment" is just an arrow
pointing in the direction of
the magnetic field inside
the loop
Hint 4: magnets attract
when their fields are in
the same direction
Hint 5: Use
different colors
for each part of
this problem!
Hint 6: Draw
your area
vectors pointing
to the left
Hint 7: just check the key
Hint 8: draw a vector
showing the direction of the
change in flux!
Statement from textbook: When the magnetic flux through a coil changes, the
induced magnetic field in the coil opposes the original flux change.
Hint 9: Consider
any vector pointing
into the page to be
positive and any
vector out of the
page to be negative
