Magnetic reconnection is a significant mechanism for phenomenon involving high energy release such as solar flares.. Post-reconnection field lines act like elastic bands under tension.. Magnetic reconnection occurs throughout the Universe Magnetopause Reconnection: The Interplanetary Magnetic Field (IMF) reconnects with the Earth䇲s magnetic field, at the magnetopause (the oute Beats.

Occurs in solar corona, magnetosphere, laboratory plasma experiments, and even at edge of solar system. Introduction. 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..
