Abstract :
One of the important functions of a micromachine working in the human body is heating for local hyperthermia. A magnetic heating system was attached to a spiral-type magnetic micromachine. This machine could work in a gel and could heat to over 50°C by applying a rotational magnetic field and an alternating magnetic field. This machine would be able to move in the internal organs and heat tissues. In addition, the transport capability of the machine was examined on the basis of the shape of the carried elements.
