The effect of magnetic fields on the water remains a highly controversial topic despite
much research focused on this topic in the past decades. However, the improvement of
water heating in a magnetic field is less controversial. The mechanism underlying this
phenomenon was studied in prior works. In this paper, use solar electric induction to
study the heating of water in magnetic fields; one distinction between induction heating
and magnetic field heating is that the convection in the water heater is varied due to the
different heating locations. Using computational fluid dynamics, it was possible to
examine the heat load in the heater during induction heating and magnetic field heating,
determine its temperature distribution, and flow rate. The heat flow in magnetic field
heating was measured over the heater base at the bottom. In induction heating, the
analysis was conducted using the distribution of heat production as determined by
electromagnetic field analysis. Simulation shows differences in convective flow in the
heater during induction heating and magnetic field heating, particularly in the early
stages of heating.
