Water treatment technology using magnetic fields, as a physical method, integrates multiple functions such as scale prevention, scale removal, corrosion inhibition, disinfection and water purification. It has the advantage of being non-toxic and no secondary pollution and is a water treatment technology with great development potentials. There are, however, substantial controversies about its treatment effects. For example, concerning the effect of magnetic fields on crystalisation process of calcium carbonate, some people believe that under the impact of a magnetic field, the speed with which calcium carbonate forms crystal grains is high, the volumes of grains small and more crystal particles compared with crystalisation measures under normal conditions; while there are other people who do not think that magnetic fields have any effect on crystalisation of calcium carbonate. The reason why these different conclusions are reached is, in the author's view, the diversity of magnetic fields, as well as the complexity and peculiarity of the ways magnetic fields to impact.
