Unformatted text preview: Problem 3 a) What is the unit of fictitious magnetic charge m q ? Explain. a) In free space, the region a x < , a y < , L z ≤ ≤ of the rectangular coordinate system is occupied by z-directed, microscopic magnetic dipoles such that the magnetization vector inside this region is given by z M M o ˆ = r . ( o M is a constant.) Determine the scalar magnetic potential produced by these dipoles on the z-axis. Problem 4 The magnetization vector in the region b r a ≤ ≤ < , L z ≤ ≤ of a cylindrical coordinate system is assumed to be o M r a M ϕ ˆ = r with o M as a constant. Use a) equivalent currents and b) fictitious magnetic charges to determine B r and H r everywhere in free space. M. Shahabadi...
