System and method for using a capsule device

A method to navigate a magnetic capsule through a target area, comprising

• introducing a magnetic capsule into the target area, said magnetic capsule has a longitudinal axis and the magnetic dipole placed inside the magnetic capsule has a magnetization direction parallel to the longitudinal axis of the magnetic capsule;
• providing an external magnetic control system comprising more than one magnetic generation means, wherein the more than one magnetic generation means are two external magnetic balls;
• moving the external magnetic control system to a first position with a first orientation, configured to move the magnetic capsule in a first movement direction, wherein the first movement direction parallel to the longitudinal axis of the magnetic capsule;
• generating a combined external magnetic field configured to deliver a force to move the magnetic capsule in the first movement direction,
• moving the magnetic capsule horizontally, forwardly or backwardly along the longitudinal axis of the magnetic capsule, by moving the two external magnetic balls horizontally, wherein the magnetization direction of magnetic capsule, a combined magnetic field direction (B) and a direction of the force F received by the magnetic capsule are all parallel to one another;
• wherein extending the longitudinal axis of the magnetic capsule, which at this point is parallel to the movement direction of the magnetic capsule, creates a center dividing line, a distance between a capsule magnetic center to a projection line connecting two centers of the external magnetic balls is x, and a distance between a center of one of the magnetic balls to the center dividing line is h.
