Magnetic field, a vector field in the neighborhood of a magnet, electric current, or changing electric field, in which magnetic forces are observable. Magnetic fields such as that of Earth cause magnetic compass needles and other permanent magnets to lin
the refs.30,31,32introduced synchrotron intensity gradient (SIG) as a way to map the magnetic fields. The fast turbulent reconnection in MHD turbulence leads to the mixing of magnetized plasma perpendicular to the direction of the local magnetic field. This results in anisotropic structures of tur...
Most of these regions are located antipodal to large basins, leading to the hypothesis that lunar rock ejected during basin-forming impacts accumulated at the basin antipode and recorded the ambient magnetic field. However, a major problem with this hypothesis is that lunar materials have low iron...
7.4.Flux lines at an anomaly. A sensor positioned on the inside (magnet side) of the pipe is typically used to measure the magnetic field adjacent to the pipe wall. At a metal-loss anomaly, the sensor records a higher flux density or magnetic field, which indicates the presence of an an...
(a) Photograph of the system, and (b) Function block diagram. The gradient magnetic field for position tracking is generated by the x- and y-gradient coils, as shown in Figure 2. The two gradient coils have the same size and coil turns. Each gradient coil consists of four elements, ...
At 20% carbonyl concentration, the magnetic field-ordered composite can be considered a promising “smart” material for the treatment of hyperthermia in the field of biomedicine [10,11,12,13]. Scientific research in the field of polymers is the driving force behind the progress of civilization....
Compelling evidence exists that magnetic fields modulate living systems. To date, however, rigorous studies have focused on identifying the molecular-level biosensor (e.g., radical ion pairs or membranes) or on the behavior of whole animals leaving a gap
The dominant plasma nonlinearity describes advection by E×B drift motions across the magnetic field B. A very early but clear paper that discussed the importance of E×B drifts to turbulent plasma transport was by Spitzer (1960). Although much neutral-fluid research has been on three-...
A theoretical description of the density wave ordered phases induced by a magnetic field in quasi-1D conductors is given in the weak-coupling limit. Within each phase, labelled by a quantum number, the wave-vector is quantised. Density w... D Poilblanc,M Héritier,G Montambaux,... - 《...
PyCrystalField can generate a crystal electric field (CEF) Hamiltonian in two ways: (1) calculating the Hamiltonian for a given set of CEF parameters, or (2) calculating the Hamiltonian from an effective point-charge model. From the Hamiltonian, PyCrystalField can then calculate: ...
