The objectives of the present research are (1) the establishment of the levitation process of a non conducting droplet due to the action of a static magnetic field, and (2) the development of a technique to transport and fix a capsule of medicine in the affected part of the body. A numerical simulation using the SOLA-VOF method and an experiment using a magnetic fluid are conducted to demonstrate the possibility of magnetic levitation of an insulating droplet. While measuring the position of the magnetic droplet, PID control is performed on the coil current and stable levitation is realized. The shapes of the levitated droplets are examined while changing the concentration and the volume of the magnetic fluid. The effects of the control constants on the process of the droplet approaching a given position are elucidated.
