During expansion, a shaft shaped "core" formed along the axis due to high field concentration (harder to deform). This core is then gradually deformed (slower than the cloud expansion) due to higher total pressure. At the same time, we see red dots of dense, cold material in the residue, they probably contain tangled magnetic field which make them harder to be further fragmented.

We also study the shocked behavior when the clump contains small scale field (with a length scale much smaller than the clump radius). The following sequence shows a clump with contained magnetic field with flat magnetic power spectrum PB(k) ~ k0, initially(left) and after 1 cloud crushing time(right).

We will also do a more realistic power spectrum with spectral index -5/3 (Kolmogorov type).
