N2 - This paper presents an experimental study on the cavity generated with water entry of a magnetic fluid coated cylindrical magnet. The permanent magnet is cylindrical NdFeB magnet with the magnetic flux density B=390mT. The kerosene-based magnetic fluid is adsorbed to the permanent magnet. This projectile collided with the surface of water in the rectangular container made of the transparent acrylic plastic. The cavity of air in water created by the impact of the magnetic fluid coated cylindrical magnet was observed with high-speed video camera system. The experiments were performed under nonmagnetic and alternating magnetic fields. The effect of the hydrodynamic forces on the cavity formation was clarified. The effect of the alternating magnetic fields on the pinch-off time of an air cavity was also revealed.
