Example 5.7; Application of Ampere’s law.
The following problem is an interesting application of Ampere’s law apart from usual applications found in honors syllabus (eg infinite straight conductor, Solenoid and Torroid). This is to be found the excellent book by Griffith on Electrodynamics. Find the magnetic field of an infinite uniform surface current K (vect) = K i-cap, flowing over the…

Maxwell Boltzmann distribution for a classical ideal gas
i. We assume a dilute gas which is enclosed by a thermally insulated container on all sides. Dilute gas in a thermally insulated container: Dilute means concentration of gas molecules is low. Insulated implies there is no reasonable flow of heat energy across the walls of the container. ii. Each molecule is assumed to be a…
