Solar flares occur when energy is converted into x-rays ,heat & supersonic fluid motion.. Energy is stored in magnetic filed lines.. Electric field changes connectivity of magnetic field lines and the energy is released.. 12/05/2022. 1. Main result and rationale. Eckner. & . Calore. 2022 . arXiv. :. . 2204.12487. 2.

For a conductor, there can be non-zero net current. Now we suppose there is such.. Then. “Conduction” current density. Magnetization gives no contribution to net current, even though there is surface current. Open: Venus – solar wind. Closed: Venus – Venus. Draped: solar wind – solar wind. Magnetic fields guide ion and electron motions. The connectivity (topology) of these field lines helps us to understand how the upper atmosphere interacts with the solar wind..
