Efficiency of Hysteresis Rods in Small Spacecraft Attitude Stabilization

Figure 1

Variation of the magnetic flux density, 𝐵, as a function of the external applied magnetic field, 𝐻, with different peak values. Depending on the applied field the variation follows a different loop, which divides the magnetization process into 3 regions: (1) reversible domain boundary displacement, (2) irreversible domain boundary displacement, and (3) rotational motion of the domains. Inserts: domain configuration during several stages of magnetization along the first magnetization curve [6, 17].
