Here is what those vortexes are and how they form

For a magnetic field pointing towards the observer, a positive charge describes a circle in the clockwise direction. For a negatively charged particle Ωc must be replaced by −Ωc in the results of this sub-section. Hence, (4.30) shows that for a
negative charge φ(t) increases with time and the particle moves in a circle
in the counterclockwise direction.
Ions produce a chiral magnetic flux tube rotating in one direction whereas electrons produce a chiral magnetic flux tube rotating in the opposite direction.
