Dynamic stabilization of high beta plasmas by axial rf current has been theoretically investigated. It is shown that higher-number modes are very easy to be stabilized. In case of m=1 mode, if there is no conducting shell, the shorter wave-length instabilities can be stabilized, but the stabilized wave-number region is very narrow. When the plasma column is surrounded by a concentric conducting shell, however, the stabilizing force of the rf image current induced in the conducting shell is so effective that the long wave-length m=1 mode can be perfectly stabilized by very small rf current.
