Abstract

This review is intended to discuss the evolution of the solar magnetic field emerging from the solar interior into the exterior with a focus on its dynamical behavior. Since emerging magnetic field goes through the dramatically changing environment ranging from a highly dense interior to a tenuous atmosphere, various dynamical processes become involved in the evolution. From a theoretical point of view, numerical simulations have been developing as a useful tool to study dynamical processes related to flux emergence. We first infer the state of magnetic field in the solar interior which is used as the preemergence state of flux-emergence simulaiton. We then show several fundamental physical processes obtained by simulations and discuss how recent theoretical modeling of emerging magnetic field has progressed to explain observations. As a topic of current interest, we also discuss the relation between flux emergence and large-scale solar activity such as coronal mass ejections.
