In this report, the magnetic dipole moment was used to determine the need for a magnetic shield for capsule endoscopy guiding device. In addition, the index of the number of layers of MSC was examined from the evaluation of the magnetic shield characteristics of the open pail can, which is attracting attention as MSC, and the magnetic dipole moment. As a result, it became clear that the magnetic guiding device needs to be magnetically shielded at 11 Am2 and above. In addition, when the shielding performance of the open pail can was evaluated, it was shown by analysis that the magnetic flux density could be reduced by up to 1.53 mT and the relative permeability was 1000. Finally, it was found that when the magnetic dipole moment of the magnetic inducer is less than 41 Am2, only the open pail can is required, and when it is 41 Am2 or more, the MSC needs to have two or more layers.
