The rupture of the assumed initial topology of toroidally nested flux surfaces needed to produce the island requires the reconnection of magnetic field lines, which can only occur with finite resistivity. | The rupture of the assumed initial topology of toroidally nested flux surfaces needed to produce the island requires the [[reconnection]] of magnetic field lines, which can only occur with finite resistivity. | ||
