  Nontrivial topology of interfaces separating anti-chiral phases in helical
magnets result in new effects as they interact with spin polarized current.
These interfces or vortex walls consist of a one dimensional array of vortex
lines. Topological Hall effect comes as a natural expectation. Also Lenz's law
will result in a new damping mechanism in these systems. We study the dynamics
of these wall interacting with electric current and use fundamental
electromagntic laws to calculate this effect. On the other hand discrete nature
of these walls affects their pinning and result in low depinning current
density. We predict the value of this currnt using collective pinnng theory.
Finally throughout this study we propose possible standard experiments that may
distinguish our theoretical findings.
