Iductance Computations of Air-Core Solenoid Magnets by FEM

유한요소법을 이용한 공심 원통현자석의 인덕탄스 계산에 관한 연구

The inductances of air-core solenoid magnets with circular cross sections depend on the geometric structure and winding number. For the calculation of the inductance of these magnets, Grover's table is normally used. This study presents a method to calculate the inductance using finite element method. The result of the computation agrees well with those found in the literature. Inductances of solenoid magnets with nonuniform winding distribution of complicated shapes can also be computed using this method.
