Bound volume current density
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
