Only when the charge is in motion will a magnetic field exert a force on it. This magnetic force increases whenever we increase the magnetic field strength, or the charge on the particle, or the speed with which the particle moves. The equation that describes these features of the magnetic ...
basic equation of magnetostaticsdirect problemellipsoidal magnetmagnetic nondestructive testingFLAWDEFECTWe consider a direct problem of magnetostatics, i.e., calculation of the strength of the resulting magnetic field inside and outside a homogeneous magnet in the form of an arbitrary ellipsoid placed...
Where Br is residual induction of magnet; X is the air gap between testing point and magnet’s surface. According to above equation, the value of magnetic field strength is affected by magnet’s grade, dimension and testing position. It should be noted that the measured value of Nickel-coate...
2) transport of intensity equation(TIE) 强度传输方程 1. One is a solution to the transport of intensity equation(TIE) based on Fourier transforms. 在不同散度值下获得一系列图像,得到两种不同相位复原算法:一种为基于傅立叶变换求解强度传输方程(TIE)得到物体的相位分布;一种为基于薛定谔波动方程的...
\(\mathbf{E \cdot B}\) is also the source term in the helicity evolution equation (Berger 1984; Berger and Field 1984) and we suggest that the rotational flows in 3D reconnection are a signature of the helicity production or decay. An exception occurs for 2D reconnection, however, because...

Based on the Fokker-Planck description of the stochastic process and entropy balance equation, we have calculated information entropy production and entropy flux at nonequilibrium state. The dependence of these quantities on time, magnetic field, and thermal bath is studied. In this context, we ...
1a, the induced magnetic dipolar pair interaction displays an anisotropic multi-polar field, either repulsive or attractive depending on the relative position of the grains, and the applied magnetic field direction. The dimensionless number that compares the strength of the magnetic interactions with ...
