Manipulation of magnetic nanorod clusters in liquid by non-uniform alternating magnetic fields
Soft Matter, 2017It is discovered that a non-uniform alternating magnetic field can induce a translational motion of an anisotropic magnetic particle or cluster near a surface. Unlike a permanent magnet pulling a magnetic particle, the particle moves away from the magnetic source with a periodic fluctuation in its trajectory that varies with a frequency that is twice ...

3D MHD Jet in a Non-Uniform Magnetic Field
Plasma Science and Technology, 2005The purpose of this paper is to present a two-phase 3D magnetohydrodynamics (MHD) flow model that combines the volume of fluid (VOF) method with the technique derived from induced-magnetic-field equations for liquid metal free surface MHD-jet-flow. Analogy between the induced-magnetic-filed equation and the conventional computational fluid dynamics ...

On synchrotron radiation in non-uniform magnetic fields
Optics Communications, 1977Abstract We study the conditions in which a charged particle in an inhomogeneous magnetic field (particularly at the edges of a “long” uniform magnet or in a “short” magnet) can emit synchrotron radiation with a spectrum extending beyond the “critical frequency”.

On the absorption matrix in a non-uniform magnetic field
Solar Physics, 1971Beckers (1969) and Staude (1969) give contradictory expressions for the absorption matrix for a normal Zeeman triplet in a non-uniform magnetic field. Beckers' result is shown to be the correct one.

Journal of Plasma Physics, 1991
A study is made of the induction of a direct field-aligned current due to Alfvén waves excited through an initial–boundary condition for an incompressible fluid with high conductivity in a non-uniform magnetic field. A simple but exact case is considered in which the direction of inhomogeneity of the magnetic field is perpendicular to that of the shear

Vacuum polarization in some static non-uniform magnetic fields
Journal of Physics G: Nuclear and Particle Physics, 1996Vacuum polarization in QED in the presence of some configurations of external magnetic fields is investigated. The configurations considered correspond to sourceless fields lying in a plane. The motion of a Dirac electron in these field configurations is studied and arguments are found to conclude that the lowest level gives the most important ...

Quantum rings of non-uniform thickness in magnetic field
AIP Conference Proceedings, 2014We consider a model of crater-shaped quantum dot in form of a thin layer whose thickness linearly increases with the distance from the axis. We show that one-particle wave equation for the electron confined in such structure can be completely separated in the adiabatic limit when the quantum dot thickness is much smaller than its lateral dimension ...

Gyrotropic thermoelement in uniform and non-uniform magnetic fields
Journal of Thermoelectricity, 2020Using computer simulation, the temperature distributions in the working medium of gyrotropic thermoelements in uniform and non-uniform magnetic fields have been determined. Temperature dependences of the efficiency of gyrotropic thermoelements in uniform and non-uniform magnetic fields are determined.

Imapct of Non-Uniform Magnetic Field on the Operation of Magnetrons
2007 IEEE 34th International Conference on Plasma Science (ICOPS), 2007Summary form only given. The magnetron is a well-known power source because of its high efficiency, low cost, compactness and small volume. In the magnetron design, a uniform magnetic field is always pursued by shaping the pole pieces connected to ordinary magnets. However, in practice, the perfect uniform magnetic field distribution is hard to achieve
