Abstract:
A technique previously used to study the effects of magnetic fields on calcium carbonate (CaCO3) precipitate is revisited in order to investigate the two most widely reported mechanisms. The laboratory-based study tested the effect of treating solutions and particulates of CaCO3 and showed that a repeatable magnetic effect on precipitation is observed, but only when CaCO3 particulates are exposed to magnetic fields, and not when a solution of sodium carbonate (Na2CO3) is exposed to magnetic fields. Issues regarding the reproducibility of the test are also discussed.
