The magnetic flux tube generated by the dynamo action is thought to rise to the surface and form sunspots at the solar surface (Zwaan 1985). To understand the rising of the flux tube and the formation of sunspots using numerical simulations, realistic physics processes such as radiation, ionization, and thermal convection need to be considered.The magnetic flux tube generated by the dynamo action is thought to rise to the surface and form sunspots at the solar surface (Zwaan 1985).

Magnetic Flux Emergence - Scholarpedia

An efficient way for magnetic flux tubes to carry a significant amount of energy is when the field lines are twisted or writhed, i.e. there is an important non-axial (mainly azimuthal) component of the magnetic flux. Every emerging flux tube forming an active region has a certain level of twist, and transports therefore magnetic energy.An efficient way for magnetic flux tubes to carry a significant amount of energy is when the field lines are twisted or writhed, i.e. there is an important non-axial (mainly azimuthal) component of the magnetic flux.
