Unformatted text preview: Physics 318 R.G. Palmer Electromagnetism 5/4/10 Final Exam 2010 Notes: For full credit you must justify what you are doing . Show all work. Pulling an obscure formula out of a hat may lose you points; you must at least say where it came from (e.g., [Jackson page 813]), or probably you should write how to show that from standard ways.

I will readily give hints, but will record what I tell you and allow for that in grading. Short Answer Questions (4 points each) 1. In a ferroelectric material, an isolated solid sphere carries a uniform polarization field in the z-direction. There is no external electric field. Sketch the position and sign of the bound charge, and also the electric field ( E ) lines in inside and outside of the sphere. 2. Outline an explanation of the difference in behavior of paramagnetic, diamagnetic, and ferromagnetic materials in terms of the origins of each effect.materials in terms of the origins of each effect....
