Figure 5

Variation of the magnetic flux density, 𝐵, as a function of the external magnetic field, 𝐻, along the initial magnetization curve, for seven different materials as is indicated in the legend. Dotted lines: demagnetization field generated inside the bodies with the demagnetization factor, 𝑁_𝑑, indicated by the label as (a) 1×10⁻⁷, (b) 2×10⁻⁶, (c) 5×10⁻⁶, (d) 1×10⁻⁵, (e) 1.5×10⁻⁵, (f) 2.5×10⁻⁵, (g) 4×10⁻⁵, (h) 1×10⁻⁴.
