Abstract

Analytical expressions are derived for the magnetometric N m and fluxmetric N f demagnetizing factors of infinitely long, hollow cylinders with uniform susceptibility in transverse uniform applied field. Whereas N m depends on both permeability μ and the ratio of the internal and external radii of the cylinder, N f does not depend on μ. The magnetic induction and magnetic field of materials with conjugate relative permeabilities μ and 1/μ are related. © 2012 IEEE.
