- Homework Statement
- In a particular region there is a uniform current density of 15 A/m2 in the positive z direction. What is the value of ~ B· d'S when that line integral is calculated along the three straight-line segments from (x, y, z) coordinates (4d,0,0) to (4d, 3d, 0) to (0, 0, 0) to (4d, 0, 0),where d = 20 cm?

This is the problem, first time i am attempting the Ampere's law problem
From the above question this is my attempt, the picture is
∫B.ds = μ*Ienc; ----> Ampere law , where Ienc is the current enclosed in the amperian loop.
I assume the circle as the amperian loop, is it correct? Can i choose cylinder also?
I am not sure but i ended up doing this,
Ienc = 15 * 0.5*0.8*0.8 (Area of triangle * current) = 4.8 Amps
∫B.ds = μ*4.8 = 4*π*4.8 *10^-7 = 60.3*10^-7; Is it correct? Please advise.
