Interaction between two flux ropes immersed in the solar atmosphere

· Astrophys. J.; (United States)
The interaction between two flux ropes immersed in a magnetized medium is studied. The method of images is used to calculate the diamagnetic buoyancy force exerted by this interaction on an individual flux rope. The results show that the presence of an external magnetic field enables the ambient magnetic stress to give rise to an attractive force between the two legs of a bipolar arch in the lower solar corona. This provides a dynamical explanation for the photospheric observation that two magnetic features of opposite polarities can move toward each other. 7 references.
