Bound currents in a cylindrical magnet. A uniformly magnetized cylindrical magnet of radius R and height H has a magnetization M = M, k parallel to the axis of the cylinder. Determine the bound volume current density J, and the bound surface current density K, for each surface of the cylinder. The behavior of magnetic fields (B, H), electric fields (E, D), charge density (ρ), and current density (J) is described by Maxwell's equations. The role of the magnetization is described below. The magnetization defines the auxiliary magnetic field H as (SI units) (Gaussian units) The behavior of magnetic fields (B, H), electric fields (E, D), charge density (ρ), and current density (J) is described by Maxwell's equations.

Web(a) Calculate the bound currents (volume and surface) and confirm that the total current flowing along the cylinder is zero. (b) Use Ampere's law to find B, both inside and outisde the cylinder. (c) Now use the modified Ampere law $ H.dl = MoIf,enc to find H, and determine B from the definition of H. Confirm that your answer agrees with part (b). http://teacher.pas.rochester.edu/PHY217/LectureNotes/Chapter6/LectureNotesChapter6.html
