چکیده
The paper presents a numerical model using finite element method to calculate the magnetic field produced by current through a helical turn, whose thickness is comparable to the winding radius. The magnetic field was determined for helical turn considering homogeneous-linear and inhomogeneous-nonlinear medium, using the finite element software package Vector Field Opera. It analyzes the numerical model, in order to optimize it, in relation to the number of finite elements spatial, the extension of domain to calculate the field, current carrying conductor length and material characteristics of medium of the magnetic field existence. Key-Words: magnetic field, helical turn, numerical models, finite element method.
