The notion of a Hall matrix, associated with a possibly anisotropic conducting material in the presence of a small magnetic field, is introduced. Then, for any material having a microstructure we prove a general homogenization result satisfied by the Hall matrix in the framework of the Hconvergence of Murat-Tartar. Extending a result of Bergman, it is shown that the Hall matrix can be computed ...

We show that the Doppler shift on whistler mode signals from VLF transmitters may be used to infer the magnetic field of an hydromagnetic wave above the ionosphere in the magnetosphere. This inferred field can then be compared with that measured on the ground. We examine one event in detail and show the data imply that a it/2 rotation of the orientation of the wave ellipse has occurred between ...

It has been predicted that, in the presence of combined radial electric field and axial magnetic field, superfluid He in a torus will have a persistent current in its ground state. This surprising result arises from non-cancellation of the Aharonov-Bohm phase shifts associated with the opposite charges in the induced electric dipole moment of the neutral He atoms. We briefly review this predict...

Abstract We study transverse-momentum-dependent (TMD) gluon distributions and factorization theorems for the gluon-initiated semi-inclusive processes at hadron colliders. Gauge-invariant TMD gluon distributions are defined, and their relations to the integrated (Feynman) parton distributions are explored when the transverse momentum is large. Through explicit calculations, soft-collinear factor...

in this paper vibration of ferromagnetic rectangular plates which are subjected to an inclined magnetic field is investigated based on classical plate theory and maxwell equations. levy type solution and finite element method using comsol software are used to obtain the frequency of the plate subjected to different boundary conditions, good agreements is obtained when computed results are compa...

This research study presents a numerical study on forced convection heat transfer of an aqueous ferrofluid passing through a circular copper tube in the presence of an alternating magnetic field. The flow passes through the tube under a uniform heat flux and laminar flow conditions. The primary objective was to intensify the particle migration and disturbance of the boundary layer by utilizing ...

A Ni-based superalloy CMSX-6 was directionally solidified at various drawing speeds (5–20 μm·s−1) and diameters (4 mm, 12 mm) under a 0.5 T weak transverse magnetic field. The results show that the application of a weak transverse magnetic field significantly modified the solidification microstructure. It was found that if the drawing speed was lower than 10 μm·s−1, the magnetic field caused ex...

The four matrices of the electrical and the energy current densities are derived for bismuthTelluride in arbitrary magnetic fields on the basis of D R A B B L E ' S six-ellipsoid-model. The scattering time will be taken anisotropic but not necessarily diagonal in the same system as the mass tensor. The starting point is B O L T Z M A N N ' S transport equation in its region of validity. These f...

has been verified experimentally when the charge moves inside a magnetic medium for which B is much larger than μ0H [9]. 3 It is sometimes preferable that the force law be given in term of the total magnetic field on the current, in which case it is generally best (in the author’s opinion) to use the Maxwell stress tensor [8]. In 1908 Einstein and Laub [10, 11, 12] argued that the force density...
