... 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...

... characterization device Finite element analysis Magnetic field Nowadays, the design of an electrical machine – whether it is a transformer or a rotating machine – can be achieved my means of several methods such as analytical methods, lumped parameter equivalent circuit and finite element method...

.... Because of the lumped parameters’ dependence upon the relative positions of the two coils, the proposed method allows identifying the circuit parameters for several configurations so substantially reducing the computational burden. Dynamic-WPTS Field-circuit model Magnetic field Finite element...

... 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...

...) determined as q=P/S, where S is the irradiated surface. In case that the surface is heated inductively (using a harmonic current-carrying inductor), the model must be extended by the magnetic field. Its distribution may be described by the phasor A̲...

...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...
