An experimental study is presented for the subsurface phenomena and the splashing produced by the impacts of magnetic fluid drops against immiscible liquid layers under nonmagnetic and magnetic fields. Magnetic fluids used in the experiments were water-based ferricolloid W-35 and its dilution with distilled water, and a target liquid was kerosene. It was found that the subsurface phenomena and the splashing of magnetic fluid drops depended on the magnetization of magnetic fluids. In the case of higher magnetized drops, the size of the subsurface cavity was very small, and the splashing was scarcely observed. On the other hand, the compound Rayleigh jet was formed during the splash of a magnetic drop on a kerosene under nonmagnetic field. It was also found that the bubbles made of thin magnetic fluid film were formed in the target liquid at a certain value of mass concentration in magnetic fluid.
