The motion of particles in the Preisach plane is the source of accommo
dation in a model recently introduced. When pulsed magnetic fields are
applied, additional effects can occur which vary with the sizes and d
uration of the pulses. There are two causes for these effects: the mot
ion of the distribution in the Preisach plane and the motion of the pa
rticles within the distribution. This paper describes this behavior qu
alitatively.
