Some features of the magnetospheric activity seem to possess low dimensional dynamics. Self-organised criticality (SOC) is often referred to as the statistical behaviour responsible for the observed distribution of the electrojet indices. One of the models extensively used for this objective is the field-reversal model. We apply the correlation dimension analysis to an implementation of the field reversal model to show that, although the field reversal model does exhibit low dimensional dynamics, quantitatively the dimension of the dynamics does not agree with that calculated from the dataset of electrojet indices. Thus, the electrojet indices statistics cannot be explained directly by this model.
