It is shown by employing a more complete Ohm's law that field-reversed plasma configurations may magnetically tear at a rate proportional to eta/sup 1//sup ///sup 2/, where eta is the resistivity. Such a growth rate obtains if the current layer width is small enough and the plasma is not too collisional, the rate reverting to the usual eta/sup 3//sup ///sup 5/ scaling otherwise. The present theory, however, assumes cold ions, an assumption that would have to be relaxed for most applications.
