Question

. (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 −
2x 3az 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.

Answer 1

explain

Answer 2

What is there to explain? You are supposed to be explaining.

Answer 3

you need to declare \(\vec H\)
