am stuck on a magnetic field problem, please help me out..
The XOY plane carries a uniform surface current density k`=50 x^ A/m. What is the magnetic field at the point z = -0.5m?
Curl B = mu0J
The Attempt at a Solution
using stokes theorem
Int[Curl B.ds`]=Int[B.dl`]= Int[mu0 J`.ds`]
i.e B=25 wb
but the answer is given 10pi.10^-6 wb.
