Phys 200B – HW5/6

Due Friday 28-Jan-05 12:00AM to Norm Paris

6-1. A cubical box consists of five grounded conducting sides. The top is also a conducting surface held at potential V₀. The length of each side is a. Find the potential inside the box.

6-2. Consider a coil wound around a sphere of magnetic permeability m. The coil is wound in a way to produce an effective surface current density of k(3cosq²-1). Find the Magnetic field in all space.

OK… the magnetic field problem did not work the way that I wanted it… Please switch this to a dielectric sphere with e and change the surface current density to a surface charge density. Find the electric potential. (Sorry)

6-3. Problem 3.7 in Jackson
