Imagine a slab of current that is infinite in x and y but finite in z with a current density ?J. The slab has a thickness 2h (it runs from z = ?h to z = +h). Assuming the current is still in the x direction and is uniform in the x and y dimensions, but depends linearly on the height (J = J0|z|xˆ) inside the slab. Find the magnetic field everywhere in space, including inside the slab.

An infinite slab of charge of thickness 10m lies on the x-y plane between z = -5m and z=+5m. The charge density, ρ, is 4 C/m3 and is a constant throughout the slab. (HINT: this is similar to what we did in class to find the E-field for an “infinite sheet” of charge… remember the cookie dough and the cookie cutter). a. Use Gauss's Law to find an expression for the Electric Field strength for any point inside the slab (-5m...

2. A thick slab, infinite in extent along r and y, has faces at th. Electric current flows within this slab with uniform current density Jox. Using Ampère's Law, find the magnetic field measured by an observer at Cartesian position (0, 0, z). (There are three regions to consider here: below the slab, within the slab, and above the slab.) Treat this as a question from Chapter 5, i.e., assume that the slab's material is non-magnetic.
