The Grad- Shafranov equation plays an important role in the analysis of the plasma equilibrium in magnetic confinement configurations such as tokamak. In tokamaks which are operating in Ohmic heating regime, the Grad- Shafranov equation can be expanded through the inverse aspect ratio parameter. Consequently, the first order of the poloidal flux function and poloidal/radial components of the magnetic field are obtained. It is possible to estimate the Shafranov equilibrium parameter in a semi-analytical approach just by means of one of the magnetic field components. In this study, the Shafranov equilibrium parameter was estimated by means of the poloidal magnetic field experimental data, measured by the Damavand tokamak magnetic probes.
