In this paper we presented comparison between two techniques in order to investigate the effects of the plasma internal inductance on plasma horizontal displacement in IR-T1 tokamak. For this purpose, a diamagnetic loop with its compensation coil, and also an array of magnetic probes were designed, constructed, and installed on outer surface of the IR-T1 tokamak chamber, and then the poloidal beta and poloidal and radial magnetic fields measured. Moreover, a few approximate values of the internal inductance for different possible profiles of the plasma current density are also calculated. Then, the Shafranov parameter and also the plasma horizontal displacement were determined. Experimental results compared. Comparing of the results on IR-T1, show that (1) by increasing the internal inductance from one, plasma column shifted inward, and also (2) IR-T1 plasma current density profile relate to the power of upsilon = 3.
