What relatively slow process allows star formation to continue past the initial magnetic hindrance?

Answer

Ambipolar diffusion, which allows neutral particles to drift across magnetic field lines.

Ambipolar diffusion is the slow process where the magnetic field, tied mainly to ionized particles, decouples from the bulk of the neutral gas, allowing the central density to increase sufficiently for gravity to overcome the magnetic support locally.
