The animations below show the field lines inside the star (the surface of the star is a sphere slighty larger than the field of view.) The colour of the field lines represents the density of the gas -- red is less dense, blue is more dense.
Case with just poloidal field
Case with just toroidal field
Case with just toroidal field - just field lines around axis
Case with both poloidal and toroidal fields
Case with both poloidal and toroidal fields - just field lines around axis
