Several Rules about the Magnetic Moment of Rotational Charged BodiesGuo-Quan Zhou doi:10.2529/PIERS061120233608 Downloads: 885 Abstract:A strict and delicate analogy relation between the magnetic moment of a rotational charged body and the rotation inertia of a rigid body about a fixed axis has been found in this paper. Based on this analogy relation, many rules and theorems about calculating the rotation inertia of a rigid body can be transplanted to field of electromagnetism and used to calculate the magnetic moment of a rotational charged body. Some principles or theorems are extended, generalized, illustrated, and enumerated. Some related examples are listed in the paper.References:1.
