What specific process allows the majority component of gas (neutral particles) to decouple from magnetic field lines, thus enabling collapse to proceed?

Answer

Ambipolar diffusion

Ambipolar diffusion is the slow slippage where neutral gas moves inward under gravity while charged particles remain coupled to the magnetic field lines, allowing a dense core to form.
