Magnetic Circuits, Air Gaps (conceptual)

[sandy.bridge]

Homework Statement

When dealing with magnetic circuits, if the question explicitly states to ignore fringing, then the flux density of the gap will equal the flux density of the core, correct? In fact, if there are ever more materials, the flux density throughout the entire circuit (series) will have the same flux, and flux density. The only thing that will vary is the permeability of each material as well as the magnetizing force, correct?

I think you are correct. Worked out examples,

see example 9.7.1
