Abstract
Ice nucleation and supercooling are controlled by the presence of magnetite particles. Magnetite decreases supercooling and promotes ice nucleation. Therefore, freezing of liquid solutions occurs at higher temperature compared to supercooled solutions. Applying a magnetic field allows control of supercooling and ice nucleation.
