“…Solenoid inductors and similar structures are widely used in high-current electrical engineering applications, such as pulse power supplies, linear induction launchers, coil guns, superconducting coils, and electrodynamic levitation systems [1][2][3][4][5][6][7][8]. The strong magnetic field of the inductor develops a strong magnetic force, which can cause mechanical stress on the support structure of the inductor, resulting in the inductor being easily deformed or even damaged.…”

A new semi-analytical expression is presented based on two integrations for calculating the magnetic force of a solenoid inductor wound by rectangular cross-section wire. The authors simplified the solenoid inductor coil to a collection of circular coils, and the current density of the coils in the radial direction which was inversely proportional to its radius is considered. The obtained expressions can be implemented by adaptive Gaussian quadrature integration with MATLAB programming. In addition, they used the filament method and the finite element method to calculate the magnetic force on the solenoid inductor coil. The correctness of the semi-analytical expressions was verified by comparing the results of the semi-analytical numerical method with those of the filament method and the finite element method, respectively. The derived semi-analytical expressions of magnetic force allow a low computational time compared with the filament method and the finite element method to a specific accuracy. The calculation results show that: the solenoid inductor coil tends to compress in the axial direction, and the axial magnetic force on the outermost coils is the largest; the solenoid inductor coil tends to expand outward in the radial direction, and the radial magnetic force on the intermediate coil is the largest.This is an open access article under the terms of the Creative Commons Attribution-NonCommercial-NoDerivs License, which permits use and distribution in any medium, provided the original work is properly cited, the use is non-commercial and no modifications or adaptations are made.

“…However, there is little research on the radial magnetic force of the coils. The magnetic force of solenoid inductors and similar structures is often analysed by the finite element method [8,[15][16][17][18].…”
