Numerical and Analytical Study of the Magnetic Field Distribution in a Three-Solenoid System
This paper investigates the magnetic fields produced by a three-coil system, focusing on how different mesh resolutions affect the accuracy of the results. Using both the Poisson solver, as well as a numerical approach based on the solution of fractional integrals, the study examines coils with dimensions of 80 mm by 160 mm and a radius of 15.5 mm, each carrying a current of 200 A. The research explores how varying mesh step sizes within the coil regions influences the simulations accuracy and convergence. The results are analyzed along a line parallel to the central axis at a distance equal to half of the solenoid's radius.. The findings emphasize the consistency of the numerical results, the compatibility of the solvers, and offer insights into further optimization strategies for more efficient simulations.
