Magnetic Interaction

Magnetic Interaction

. A pair of oppositely-directed, twisted coronal loops come in contact, releasing magnetic energy to power a solar flare. Arrows indicate the direction of the magnetic field lines and the sense of twist. Such magnetic encounters can occur when newly emerging magnetic fields rise through the photosphere to merge with pre-existing ones in the corona, or when the twisted coronal loops are forced together by underlying motions.
