Will Magnetic Putty Form a Cube or Sphere When Swallowing a Rare Earth Magnet?

[KenCurious]

I've attached a video of magnetic putty swallowing a rare Earth magnet. Will the resulting shape of the putty be cubed like the rare Earth magnet (equal distribution of magnetic forces along the surface) or will the shape be spherical (weird magnetic forces along the edges of the cube)?

Just guessing - the magnetic putty will interact with the lines of magnetic flux, to create the minimum-energy configuration. The flux lines will be modified by the putty. The end result is likely to be somewhat spherical but modified by the shape of the magnet, perhaps with some flattening at the magnet poles as the flux lines bend away sharply there.
