Question

how to set up a?

D7.4. (a) Evaluate the closed line integral of H about the rectangular path
P1(2, 3, 4) to P2(4, 3, 4) to P3(4, 3, 1) to P4(2, 3, 1) to P1, given H = 3zax − 2x3az A/m. (b) Determine the quotient of the closed line integral and the area
enclosed by the path as an approximation to (∇×H)y. (c) Determine (∇×H)y
at the center of the area.
Ans. 354 A; 59 A/m2; 57 A/m2
