A current distribution produces a magnetic flux density, B = (-6xz + 4xy + 3xz)a, + (y + 6yz - 4xy2)ay + (y - z - 2x-z)az Wb/m. Calculate magnetic flux through the surface defined by y = 1,0 x, z 2. An infinitely long filamentary wire carries a current of 5 A in the z-direction. Calculate the magnetic flux through the square loop described by 1 p 6 m and 0.1 z 2.1 m. A current distribution gives rise to the vector magnetic potential A = 2yz ax + xy ay - 6xyz a, Wb/m. (i) (ii) Compute the magnetic flux density, B Let a loop be described by y = 1 m, 0 x4 m, 0z5 m. By computing the flux through this loop, show that B. ds = A.dl.
