A thick slab extending from z=-a to z=+a carries a uniform volume current J=Jx (fig 5.41 attached). Find the magnetic field, as a function of z, both inside and outside the slab.© BrainMass Inc. brainmass.com July 16, 2018, 12:28 am ad1c9bdddf
let the width of the slab is b.
Outside the slab: (|z| > a)
We draw a rectangle surrounding the slab (Ampere's circuit).
