AB: This paper analyzes the large-scale fluctuations of the H-component magnetic field at Earth's equator during the period from 1981-2002. A multifractal characterization is applied to the SYM-H index data and it is found that previous suggestions that SYM-H is monofractal are accurate. It is demonstrated empirically that the underlying mechanism of SYM-H, presumably ring current energization and relaxation, can be captured by recurrent iterated function systems (RIFS). The RIFS model is used to simulate the measure representation of SYM-H.
