**[SOLVED] griffiths 6.5**

## Homework Statement

A uniform current density [itex]\mathbf{J} = J_0 \hat{\mathbf{z}}[/itex] fills a slab straddling the yz plane x=-a to x=+a. Find the magnetic field inside the slab.

This is part of Griffiths Problem 6.5.

## Homework Equations

[tex]\nabla \times \mathbf{B} = \mu_0 \mathbf{J}[/tex]

[tex]\int \mathbf{B} \cdot d\mathbf{l} = \mu_0 I_{enc}[/tex]

## The Attempt at a Solution

I first need to find the direction of B. What can I use to do that? The right-hand corkscrew rule does not seem to help here!
