A Field-Reversed Configuration (FRC) is formed by applying Rotating Magnetic Field (RMF) much larger than the axial magnetic field to a cylindrical glass vacuum chamber filled with 10Pa Argonne gas without a pre-ionization. The FRC with the plasma density 2.2x1019m-3, the temperature 8.0eV, the separatrix length 0.45m and the separatrix radius 0.035m is sustained for the notably long period 40msec. During the period the RMF is fully penetrated into the center and drives the current with peaked profile near the field null. The 0-component of RMF plays a major role in a radial force balance between the plasma pressure and the magnetic pressure.
