1. A system for moving a capsule within the body of an animal comprising:

  • a capsule dimensioned and shaped to move within the body of the animal;

    mechanically coupled to the capsule, an anisotropic magnetic component to orient the capsule in relation to an applied magnetic field;

    a detector to determine the location of the capsule within the body; and

    a magnetic field generating system external of the body responsive to the detected location of the capsule for generating a three dimensionally oriented field within the body to move the anisotropic magnetic component and thereby the capsule within the body.
