磁気誘導磁石保管用磁気シールド設計のための簡易解析モデルの検討

抄録

In this report, we focus on the magnetic dipole moment and the charge model to model the magnetic shield case of the capsule endoscope guiding device and use the two to propose a cylinder of ϕ100×25 proposed by Matsuhashi. The area where the magnetic flux density distribution is different was clarified. As a result, it was suggested that the charge model is effective near the magnet (l = 0 to 0.3 m) and the magnetic dipole moment is effective far from the magnet (0.4 m ≤ l).
