Flux transfer

Definition

Flux transfer refers to the process by which magnetic field lines are reconfigured and exchanged between different plasma regions, resulting in the transfer of magnetic flux. This phenomenon is critical in understanding magnetic reconnection, where the interaction of magnetic fields leads to energy release, particle acceleration, and changes in plasma dynamics, often observed in space weather events such as solar flares and geomagnetic storms.
