...Ana N. Vuckovic; Natalija V. Ivkovic; Isidora N. Jovanovic; Mirjana T. Peric; Nebojsa B. Raicevic Purpose The purpose of this study is to provide an accurate approach for calculating the magnetic field generated by a permanent ring magnet with a trapezoidal cross-section. Recognizing...

... The calculation of the magnetic field has been validated for various values of slip and iron permeability. All electromagnetic quantities were compared with those obtained using a two-dimensional finite-element method. The semianalytical results are satisfactory compared with the numerical results, considering...

... method is involved, one of the Achilles’ heel lies in the behavioral model that is used to represent the constitutive equations, in particular the relation between the magnetic field H and the magnetic flux density B . Several behavioral models are reported in the literature, each one allowing to take...

... and numerical conformal mappings such as the Schwarz-Christoffel (SC) mapping are used for magnetic field analysis due to the permanent magnets and the armature reaction in one slotted air gap. The field solution in the slotted air gap is obtained through the modulation of field solution in one slotless air-gap...

...Hartmut Popella; Gerhard Henneberger The resolution of magnetic resonance imaging, commonly known as MRI, depends on the homogeneity and field strength of the used primary magnetic field \vecB₀ over the volume of interest. In clinical tomographs...

...Jussi Kaisjoki; Kimmo Forsman; Aapo Koski; Lauri Kettunen In this paper, a hybrid formulation for solving time harmonic eddy current problems in terms of magnetic field h is considered. In particular, we discuss some properties of the implicit boundary condition on the discrete level...

...M. Berlec The paper shows a method for 3D magnetic field calculation. The method was developed from previously published 2D method of current sheets. The method is based on magnetic homogenisation of the space. Only one permeability appears inside all magnetic problem space after the homogenisation...
