The Design and Simulation of Spiral Planar Coil in COMSOL Multiphysics

The aim of this paper is to calculate the inductance of a spiral planar coil. COMSOL Multiphysics software was used to calculate the inductance. The article describes the design of the spiral planar coil in the simulation program with the results of the simulation. Next it is described the design of the spiral planar coil based on the simulation parameters and its production of a 3D FDM printer using a special metal-polymer composite containing a copper particles. The results obtained by simulation, calculation using the equations and the produced real spiral planar coil were compared.
