A Discussion On Length and Cross Section of Magnetic Circuit of Circle Core

摘要

In this study, a circle magnetic body of random limited sized cross section was discussed to calculate errors when dealing with magnetic flux, inductive quantity of circle circuit and ampere turn with mean magnetic circuit length and geometric cross section, effective magnetic circuit length and effective cross section of circuit length and effective cross section of circle magnetic body were definited, and strict formula were inferred to calculate relevent physical quantity.
