In the present research, aluminum oxide- water (Al2O3-H2O) nanofluid free convection due to magnetic forces through a permeable cubic domain with ellipse shaped obstacle has been reported. Lattice Boltzmann approach is involved to depict the impacts of magnetic, buoyancy forces and permeability on...
Here χm is called the magnetic susceptibility and is a constant characteristic of the material. The previous relation is another example of a constitutive equation and is not a fundamental equation of electromagnetism. Again, it turns out that the magnetic energy density of a system of charges ...
13. The Landau–Lifshiz–Gilbert equation is solved using the fourth-order Runge–Kutta method. The NiFe disc contains a magnetic vortex structure of 4.2 µm in diameter, and thickness 40 nm. The saturation magnetization was taken to be stant K4π =M 0s, =an 1d Tt,...
This paper presents the normal force phenomena for static and steady shear mode in magnetorheological (MR) fluid. The results of the study show that, in the static mode, with the magnetic flux density increasing, the normal force will increase until the maximum, and then reduce to a steady ...
In case of a contact between two spherical particles of different radii, R1 and R2, the van der Waals forces can be calculated from Equation (1) assuming: (2)R=R1,2=R1R2/R1+R2 In reality, particles are never as ideal as indicated and have some realistic configurations [25], as shown...
To solve this problem, a new hybrid radial magnetic bearing structure has been proposed. The nonlinear model and linearization equation of the new hybrid radial magnetic bearing capacity has been established by current molecular method and virtual displacement theorem. It is found that the permanent ...

As a result, temporal non-uniformity in electrical permittivity and magnetic flux will be created. The intensity of an unbalanced force regime at higher superheat will be magnified, which will lead to bubble oscillation. However, the influence of these energy fields on boiling thermal performance ...
The structure and dynamics of the solar corona is dominated by the magnetic field. In most areas in the corona magnetic forces are so dominant that all non
