the electrolyte solution magnetic flux lines are conventionally drawn more closely spaced when crossing through a region containing paramagnetic material an effect of which is to make permeability in that region higher than in air flux lines are drawn more widely spaced when crossing through a region that is of lesser permeability than air because of containing diamagnetic material contemporary equipment exists which can and should be used to detect and plot induced non uniform magnetic fields whenever it may not be readily apparent by inspection of magnetoelectrolysis cell lay out of where differentially permeable regions within an electrolyte solution locate during cell operation hall probe gaussmeters of high sensitivity and small dimensions may be inserted at appropriately selected points plotting of induced magnetic fields can also be done using medical imaging technology such as described in u s pat no 5 073 858 december 1991 to mill for magnetic susceptibility imaging msi u s pat no 5 738 837 issued apr 1998 to klaveness et al for lanthanide paramagnetic agents for magnetometric imaging is one of many disclosures of medical imaging techniques and devices which are readily adapted to mapping magnetic susceptibilities gradients that drive convection in magnetically enhanced cells and batteries featuring intentionally increased extent of paramagnetic diamagnetic contrast.
