Question

In a particular region there is a uniform current density of 14  A/m2 in the positive z direction. What is the value of ʃ B(vector) dot d s(vector) when that line integral is calculated along the three straight-line segments from (x, y, z) coordinates (7d, 0, 0) to (7d, 2d, 0) to (0, 0, 0) to (7d, 0, 0), where d = 19 cm?
