whereas the force between like poles is repulsive. The magnetic field is sometimes referred to as magneticinductionor magnetic flux density; it is always symbolized byB. Magnetic fields are measured in units oftesla(T). (Another unit of measure commonly used forBis thegauss, though it is no ...

It was found that, when Li4 assumes a planar structure, spin singlet state is lower in energy. However, when Li4 forms a tetrahedron, the preferred spin is a triplet, that is, the magnetic moment of Li4 is 2 μB. That a cluster with the same size and composition can either be ...
This magnet exhibits high magnetic flux density, high coercivity, which makes it suitable for various high-end applications. Power generation end-use industry segment to be the second largest segment in the advanced magnetic materials market, in terms of value. The use of advanced magnets in the...

Here, diagonal elements of the density matrix correspond to the populations of the different energy levels in the system. The advantage of this formalism is that it allows to easily change the transition rates to accommodate for different scenarios. All numerical simulation were erformed using the ...
This is inferred to be one of the reasons why density sharply decreases from the chromosphere to the transition region and the corona. The different solar-cycle behaviors of different categories of magnetic elements imply that their origins may be different. At the solar shallow subsurface (the ...

In basic units, 1 T = N·A−1 m−1. However, it is also common to use the unit gauss of the CGS system, named after the German mathematician Carl Friedrich Gauss (1 T = 104 G). • Magnetic flux density: tesla (T) for SI; gauss (G) for CGS Another vector magnitude ...
Magnetic susceptibility refers to the ability of human tissue to change the density of the static magnetic field [11]. Magnetic susceptibility is seen in regions where there is an abrupt change from tissue to air (as in the brain) at high fields. When the field homogeneity is disturbed in ...
