Energy release Energy release occurs in stressed magnetic fields,
{"Image DocumentName": "Energy release Energy release occurs in stressed magnetic fields,", "Image ImageDescription": "but there is much difficulty in accounting for the rapid. nature of the release. The basic problem is that high-temperature coronal plasma, especially for flares, has an extremely large electrical. conductivity \u03c3 (comparable to the conductivity of solid. copper at room temperature) or equivalently small magnetic. diffusivity \u03b7 = 1/(\u03c3 \u03bc0) . The energy release timescale appears to be of the order. of years rather than the observed seconds or minutes.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
