To improve the performance of ice thermal storage systems, the problem of freezing on the cooling surface must be addressed. One of the authors has proposed a new ice making method in which a magnetic fluid prevents water from freezing on the cooling surface. Thus, we investigated experimentally the effect of shape control of magnetic fluid using a magnet of freezing of supercooling water. The shape changes and motion of magnetic fluid, which are controlled by controlling the magnetic field, have a slight effect on the supercooling phenomenon. However, the exposure of the cooling surface covered by a film of magnetic fluid reduces the time from controlling the magnetic field until freezing to a few seconds. Therefore, it is possible to use an electric magnet.
