These channels follow the length of the stone. Magnetic force (like water) passes through this channels.

After a split, these channels continue to function.

Does the position of the stone change the movement of the vessel in which the stone is placed?

Cabaeus’ instruments are similar to Gilbert’s. But Cabaeus follows (in his emphasis on channels) another line of investigation. It leads him towards an understanding of magnetic forces as flux through channels.
