The purpose of this report is to design a magnetic guiding device for guiding capsule endoscopes. The goal is to obtain 17 mT at a distance of 100 mm from the guiding device. Furthermore, the device needs to be lightweight. Two magnetic guiding devices were proposed. The one with 4 magnets arranged was 1475 g, and the one with donut type was 1229 g. In both cases, a magnetic flux density of 17.1 mT was obtained at a distance of 100 mm. However, the magnitude of the magnetic gradient was different, and the magnetic force obtained was 5 mN for the 4 cylindrical magnets and 5.9 mN for the donut type.
