Concept Question 5-2: The ends of a 10 cm long wire
carrying a constant current I are anchored at two points
on the x axis, namely x = 0 and x = 6 cm. If thewire lies
in the x–y plane in a magnetic field B = ˆyB0
, which of
the following arrangements produces a greater magnetic
force on the wire: (a) wire is V-shaped with corners at
(0, 0), (3, 4), and (6, 0), (b) wire is an open rectangle
with corners at (0, 0), (0, 2), (6, 2), and (6, 0).
