Hi,
I was wondering whether anyone could help with this question:
For an iron ring of rectangular cross-section with mean radius R, radial thickness 2r and height t: (a) derive an expression for the permeance P of the iron ring, and (b) obtain an expression for the approximate permeance Pʹ of the ring if R>>r.
Thanks a lot, any help is appreciated.
