Fem – based simulations of selected setups of magnetic field tomography

Abstract

The aim of this study was to prepare a computer simulation of four selected systems for magnetic field tomography. The first three contain four, six and eight magnets arranged concentrically around a rotating cylinder with a hole. The subject of the last simulation is a pair of magnets, between which the tested object is moving. In this case, the object is moving linearly between the magnets and in each step rotates around its axis. Analysis of the results was carried out. A summary of the changes in the amplitude of magnetic field strength depending on the shift angle and diameter of the hole in the object considered has been presented.
