Magnetic Connection

Magnetic Connection

. Material moves in both directions away from an explosive center (left), observed as Doppler shifts when the SOHO SUMER instruments scanned across it. This is explained by a magnetic reconnection model (right), involving magnetic field lines (dashed lines with arrows for magnetic direction) and plasma flow (solid arrows). Material flowing inwards from each side, at speeds much less than the Alfvén velocity, VA, carry magnetic fields together. At the center X, magnetic fields that point in opposite directions meet and join together, hurling material in both directions away from the point of magnetic contact at about the Alfvén velocity.
