Abstract:
Comparison between measurements on spheres and cylinders shows that a short cylinder with axial ratio (length/diameter) ≃0.9 and susceptibility ≃0.8 (cgs) has an effective demagnetizing factor N ≃ 3.7 both in the axial and radial directions. Hence, for a short cylinder with high susceptibility, the sum of the effective demagnetizing factors in three mutually perpendicular directions is less than 4π. This is important to know e.g., when determining the magnetic properties of highly magnetic magnetite ore samples.
