The runaway transport is used to probe the magnetic fluctuation level for TEXTOR disruption plasmas. A zero dimensional model of the current quench including the generation of runaway electrons has been applied to simulate the experimental current evolutions during major disruptions [Plasma Phys. Control. Fusion 50 (2008) 105007]. According to the loss rate of runaway electrons used in the fitting parameter of the zero dimensional model, the magnetic fluctuation level in TEXTOR is derived. It is found that the magnetic fluctuation level is in the order of 10-5, and it increases with the atom number mixed into the plasma.
