A conducting rod with a square cross section (3.0 cm × 3.0 cm) carries a current of 60 A that is uniformly distributed across the cross section. What is the magnitude of the (line) integral around a square path (1.5 cm × 1.5 cm) if the path is centered on the center of the rod and lies in a plane perpendicular to the axis of the rod?
A) 14 μT ⋅ m
B) 75 μT ⋅ m
C) 19 μT ⋅ m
D) 57 μT ⋅ m
E) 38 μT ⋅ m
