Superconducting magnets are used very extensively in modern science and technology to produce high intensity magnetic fields. In many application, magnets are used in non-dc conditions and are subject to current ramping. The magnets studied in this paper were intended to be used in the Superconducting Supercollider with a ramping rate of 4A/sec and a maximum current of 7000A. Due to the effects of eddy currents and parasitic capacitance, the electrical characteristics of superconducting magnets are not completely inductive; instead, they are frequency dependent functions. This paper develops a method of accurately measuring the ac characteristics and determining the circuit models of superconducting magnets that characterize the eddy currents and the parasitic capacitance. This measurement method can be used to analyze eddy current and the resulting circuit model can be used to study the transmission line effect of long magnet strings.
