• Purpose – The purpose of this paper is to create computer models of magnetic micro‐ and nano‐fibres. The fibres are the base of textronics devices, such as sensors and actuators. The authors show how one can avoid painstaking work during manufacture process by initial preparing of computer models.

  Design/methodology/approach – The paper presents correspondence between finite element method (FEM) and reluctance network method (RNM). The smooth transition is possible, due to homogeneous models of magnetic micro fibres based on FEM.

  Findings – The paper describes the solution to accelerated designing and manufacturing process of magnetic micro‐fibres; it describes also how magnetic permeability of such fibers can be calculated and how to perform a homogenisation in models.

  Originality/value – The authors present a new way of modelling magnetic micro‐fibers by combining FEM with RNM. So far, only calculations for the B/H curve of magnetic micro‐fibers have been performed, yet authors propose an innovative way for determination of magnetic micro‐fibers' parameters. Homogenisation of finite element models is the crucial part in the process of combining two different numerical methods.
