MAGNETIC FIELD GENERATION APPARATUS AND CAPSULE MEDICAL DEVICE GUIDING SYSTEM

摘要

A magnetic field generation apparatus for generating a guiding-magnetic field which is a magnetic field for magnetically guiding a target object includes a plurality of permanent magnets configured to generate a magnetic field, and a switching unit configured to change relative relationship of the plurality of permanent magnets to switch between a first state in which the plurality of permanent magnets generate the guiding-magnetic field in a predetermined region and a second state in which a strength of the guiding-magnetic field in the predetermined region is less than a strength of the guiding-magnetic field in the first state.
