THE RESISTIVE TEARING MODE IN A WEAKLY 2-DIMENSIONAL SHEET PINCH
The influence on the resistive tearing mode of a weak normal component of the magnetic field B-n in a sheet pinch is examined. The dispersion relation in the high conductivity limit is derived in closed analytical form and it is shown that the normal magnetic field exerts a stabilizing influence. For values of B-n scaling like eta**2/5, where eta is the resistivity, the results obtained relate to recent numerical calculations of Nishikawa and Sakai for finite B-n. In the very weak ordering with B-n scaling like eta$u4/5, the previous analytical result of Janicke is recovered.
