Abstract

Fluxmetric and magnetometric demagnetizing factors, Nf and Nm, for cylinders along the axial direction are numerically calculated as functions of material susceptibility χ and the ratio γ of length to diameter. The results have an accuracy better than 0.1% with respect to min (Nf, m, 1 - Nf, m) and are tabulated in the range of 0.01 ≤ γ ≤ 500 and - 1 ≤ χ < ∞. Nm along the radial direction is evaluated with a lower accuracy from Nm along the axis and tabulated in the range of 0.01 ≤ γ ≤ 1 and - 1 ≤ χ < ∞. Some previous results are discussed and several applications are explained based on the new results. © 2006 Elsevier B.V. All rights reserved.
