Physics 6346, Electromagnetic Theory I Fall 2000 Homework 11 (the last one!) Due Friday, December 1, 5 p.m. Reading: Chapters 5 and 6 of Jackson . The some of the material in Chapter 6 be covered on the final; I will suggest some problems to work (not to be handed in) so that you may familiarize yourself with this material. 1. Jackson 5.13. 2. Jackson 5.17. 3. Superconducting levitation . A now common lecture demonstration involves levi- tating a permanent magnet above a superconducting disc (usually YBCO, one of the new high temperature superconductors). We’ll idealize the problem by assuming that (a) B = 0 inside the superconductor; (b) the superconductor is infinite in extent, oc- cupying the half-space z< 0; (c) the permanent magnet can be approximated by a point magnetic dipole with dipole moment m , which makes an angle θ with the z -axis; (d) the magnet can be considered to be a point mass of mass M . (a) This problem can be solved using the method of images. What image dipole is
