要約(英語): In this report, the validity of the theoretical formula for the magnetic force acting on a steel ball from a Magnetic guiding magnet is examined by t-test. Also, considered whether the theoretical formula can be applied to the calculation of the magnetic force. As a result, the validity was shown because there was a very strong correlation between the analytical value and the calculated value of the magnetic force at the significance level α of 1%. Then, it was suggested that the calculation by the theoretical formula of the magnetic force can be applied at 80 < l ≤ 120 mm. And the constant of the capsule endoscope estimated as 1.8×10-12 H･m2.
