Abstract

A useful classification of fabricated ferromagnet sets can be inferred from graphs plotted with theH cB/B r andH cI/B r ratios of individual magnets which are closely similar in material composition, properties and fabrication history. For each defined set, a mean characteristic curve is obtained which may be regression fitted by (i) a logarithmic and (ii) a second-order polynomial expression. Both these regression analyses are here further discussed with the resulting suggestion that the limiting type 1 and type 2 classification of ferromagnet sets can be associated with two modes of magnetization in which the corresponding domain patterns recall, respectively, the laminar and turbulent flow patterns of a fluid system analogue.
