## Homework Statement

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?

## Homework Equations

Curl B = mu

_{0}J

## The Attempt at a Solution

using stokes theorem

Int[Curl B.ds`]=Int[B.dl`]= Int[mu0 J`.ds`]

B. 2.pi.(.5)=50.pi.(.5)^2

i.e B=25 wbbut the answer is given 10pi.10^-6 wb.
