The relationship between the atomic magnetic moment and magnetization intensity
M is as follows:
4 that the yield stress is proportional with the magnetization intensity of particles.
4 and the relationship between magnetization intensity and magnetic field intensity explained by electromagnetism, the previously mentioned relationship among yield stress, magnetic field intensity H and saturation magnetization intensity [M.sub.s] can be successfully explained, which also proves the validity of chain-like flocculation theory of magnetism agglomeration.
Magnetization decay of strongly coupled carbons was described by the Gaussian decay time constants ranging from 22 to 26 [micro]s with a fraction of about 47-95 % (the Gaussian initial magnetization intensity, Table 4).
The Lorentzian decay time constants in this region varied from 44 to 308 [micro]s with initial Lorentzian magnetization intensity of 5-53 % for weakly coupled aliphatic/cyclanic carbons.
where [sigma] is surplus density; [J.sub.x], [J.sub.y], [J.sub,z], are the components of a magnetization intensity vector; [y.sub.1], [y.sub.2] are parameters of extension; [x.sub.k], [z.sub.k] are coordinates of angle points of the approximating polygon; N is the number of sides (angle points).
The geometrical parameters of the objects were selected simultaneously with the value of magnetization intensity of separate bodies and the linear background coefficients.
where [[mu].sub.0] is the permeability of vacuum, [V.sub.1] is the average volume of magnetic particles, [V.sub.1] = 4[pi][r.sup.3]/3, and M is magnetization intensity:
The influence of yield stress by magnetization intensity of magnetic particle and magnetic field strength were analyzed, respectively.
