The technology of capsule endoscopy becomes very popular nowadays for its painlessness, effectiveness, usability and uniqueness. In this paper, a magnetically based controllable wireless endoscope capsule is reviewed. A capsule contains magnets in the shape of doughnuts, which enables to control it by means of magnetic setup and control panel. A setup contains superconducting magnet, which provides the high intensity of magnetic field, and this enables to examine patient of any constitution. The external control over the location of a capsule is conducted by the effect of low frequency or even steady magnetic field, which does not have side effect and is able to penetrate freely with biological tissue without significant weakening.
