This article deals with the security issue of the endoscopic capsule control and movement in human body using external magnetic field. The authors describe four different variants of power connection to the magnetic coil: direct connection with the source output on resistance; direct connection with the source output in the opposite phase; oscillating circuit in critical mode; oscillation circuit with the output on resistance. Their advantages and disadvantages are considered. The analysis of the capsule movement and its control characteristics for each of the listed options of the magnetic coils powering is presented. https://www.biotech-asia.org/vol13no4/analysis-of-magnetic-endoscopic-capsule-movement-in-human-digestive-tract/ magnetic coils powering; security of endoscopic capsule movement; movement calculation
