What process allows neutral matter to fall inward while charged particles and the magnetic field lag behind?

Answer

Ambipolar diffusion.

Ambipolar diffusion is the mechanism where the neutral components of the gas decouple from the magnetic field lines, allowing the mass destined to become a star to continue collapsing inward while the charged components and field lag.
