The coalescence instability so far has been analyzed for the Finn-Kaw modelin which parallel currents in neighboring islands tend to attract each other. Thecurrent distribution of magnetic islands resulting from the compressible tearingmode, however, is or>r>osite to that of the Finn-Kaw model. It was found bysimulations that the coalescence instability does not take place for magneticislands generated by a tearing mode instability. An apparent coalescence isinduced by an external force, but it appears to reflect the growth of the lineartearing mode instability with the wavelength longer than the original one.
