The ends of a 10-cm-long 1 carrying a constant current I are anchored at two points on the x-axis, x = 0 and x = 6 cm. If the wire lies in the x—y plane in a magnetic field B = B0, which of the following arrangements produces a greater magnetic force on the wire: (a) wire is V-shaped with comers at (0, 0), (3, 4), and (6, 0), (b) wire is an open rectangle with comers at (0, 0), (0, 2), (6,2), and (6, 0).
