Abstract
A generalized analytic representation for the magnetic field and current density profiles in a reversed‐field pinch (RFP) is proposed. These profiles have zero current density at the wall and finite plasma pressure. The profiles are characterized by two free parameters here taken to be the field‐reversal parameter (F) and pinch parameter (Θ). From the profiles, many useful quantities such as magnetic energy, beta, inductance, resistance, and Ohmic input power are calculated. These quantities provide a basis for analyzing experimental data and performing electrical circuit modeling of RFP discharges.Keywords
