Endoscopic capsule for navigating inside gastrointestinal track of patient e.g. human, magnetic unit with dipole moment that produces dipole field, where part of field with orientation anti-parallel to moment penetrates via induction coil
The capsule (7) has an induction coil (2) with soft magnetic ferrite cores (3a, 3b) and supplying energy to the capsule. A magnetic unit (4) interacts with an external magnetic field, and has a magnetic dipole moment (6). The dipole moment produces a magnetic dipole field, where a part of the field with the orientation anti-parallel to the magnetic dipole moment and perpendicular to an induction coil longitudinal axis penetrates through the induction coil. The field intensity of the dipole field corresponds to the field intensity of the magnetic field in the induction coil.
