“…This approach is equivalent to restore the Ampere's law in the matrix and vector coefficient of (9) and is explained in [14]. The combination of two very simple models (a reluctance network and a MoM) for two different cases of operation modes (saturated and nonsaturated) can thus lead to accurate modeling of complex devices.…”

This paper proposes a review of the magnetostatic moments method (MoM) applied to model electromagnetic devices. This method is now well-known for its "light weight" and its simplicity of implementation. Its main advantages are the nonrequirement of an air region mesh and a coarse mesh of the ferromagnetic material. It leads to very fast resolution and very accurate field, force, and moment computations. The paper proposes a state of the art of this approach and shows some efficient realizations.Index Terms-Magnetization identification, magnetostatic moment method, point-matching approach, simplified moment method.

“…The field in the sheet is mainly tangential and constant through the thickness of the shell [10]. Equation (13) becomes then (14) The shell needs thus to be meshed only by surface elements (elements are not meshed in the thickness). Charges are then located on segments delimiting the surface elements.…”

“…Therefore, it is almost impossible to perform a real-time calculations using finite element method, because it takes a large calculation time. Therefore, the Biot-Savart's calculation method [8] and the magnetic moment method [9] were adopted for computation in the proposed visualization method.…”

A Computer Aided Education System Based on Augmented Reality by Immersion to 3-D Magnetic Field

An immersive real-time visualization system of 3-D magnetic field for educational purposes is presented. This immersive visualization system is based on augmented reality technology. The proposed system provides observation of a magnetic field distribution and its stereoscopic vision in 3-D space using head mounted display. To improve the visualization capabilities, a new real-time method for drawing magnetic flux lines in 3-D space is developed and presented in this paper. It enables a user to easily observe and grasp a magnetic field generated by multiple sources (e.g., magnets and/or multiple coils) in an augmented 3-D space. Additionally, it permits a user to freely and interactively move the magnetic sources within the visualization space and to observe the magnetic fields interference in real-time. As a result, one can intuitively and easy visualize, observe and grasp the magnetic field even in 3-D space

“…For a magnetostatic problem consisted of some ferromagnetic regions and coils supplied by currents, the magnetic field can be expressed as the sum of the external field (H ext ) and the reduced magnetic field (H r ), which derives from the magnetic scalar potential [6] H = H ext + H r = H ext − gradφ (4) with for the magnetic scalar potential…”
