Inside a square conductive material, a static magnetic field is present H(xy.z)=0 ay - 2z a,+y a: (A/m). We are looking to evaluate the current circulating inside the conductive material. The amperian loop is shown in the figure below. The current I (A) using the left or the right side of stokes theorem equals: z A(0,1,3) D(0,3,3) Amperian loop B0,1,1) c0,3,1) y Conductive material Select one: O a. None of these O b. 12 A O c4A O d. 8 A
