Reversed field pinch (RFP) plasmas have been formed in a TS-3 device and an ohmic heating current drive was applied to support the plasma. In such condition, it was found that the direction of the toroidal field induced by the plasma current naturally inversed. A magnetic structure was finally formed like the spherical tokamak (ST) in which the direction of the toridal field induced by the plasma current is the same as the field generated by the external coil. To understand the dynamical change of the magnetic structure in this process, the toroidal field distributions, safety factor profiles and the profiles of plasma pressure are shown. All of these results indicate the transition phenomena of the magnetic structure from REP to low q ST. This phenomenon is also consistent with the latest report from another organization (Himeji Institute of Technology).
