The ratio of amplitude of magnetic field to the amplitude of electric field for an electromagnetic wave propagating in vaccum is equal to the reciporcal of speed of light in vaccum. i.e,(B(0))/(E(0)) = 1/c
Aims. Only for very few beta Cephei stars has the behaviour of the magnetic field been studied over the rotation cycle. During the past two years we have obtained multi-epoch polarimetric spectra of the beta Cephei star V1449 Aql with SOFIN at the Nordic Optical Telescope to search for a ...
1a). To select robust observations of PKiKP and PcP with high signal-to-noise ratios (SNR), we retain waveforms either with an SNR ≥ 2.0 for single traces or coherent signals on record sections observed at dense arrays. SNR is defined as the ratio of the peak amplitude of PcP or...
The experimental results have been compared with numerical curves obtained by integrating the nonlinear diffusion equation for the magnetic field inside the sample with different flux creep models. It has been proved that the AC field amplitude dependence have to be included in the existing models in...
Magnetization promoted activity of magnetic catalysts towards the oxygen evolution reaction (OER) has attracted great attention, but remains a puzzle where the increment comes from. Magnetization of a ferromagnetic material only changes its magnetic domain structure. It does not directly change the spin...
Comparing the distribution difference of vertical 调平固液界面平坦度的方法resistivity of single crystal head and tail The method of adjusting plainness of solid-liquid interface 杂质条纹、生长层、平坦界面生长层形状、旋转性条纹、旋转 性表面条纹
In the equations for Figure 1c which follow, the turns ratio N refers to the entire secondary winding. V 4 = N V 1 , and V 2 = V 3 = N V 1 / 2 When the two halves of the secondary are connected to equal terminating impedances Z 2 and Z 3 , then ...
What is the electric field amplitude of an electromagnetic wave whose magnetic field amplitude is 1.9 mT? Electric Field: The amplitude of the electric field can be calculated as the product of the speed of light and the amplitude of the magnetic field. The electri...
1c). We investigated the local and distant tSMS after-effects by quantifying the amplitude of low-frequency fluctuations (ALFF), the regional homogeneity (ReHo), and the whole-brain seed-based functional connectivity using left and right SMA regions of interest (ROIs). Fig. 1 Experimental ...
The modulation effect in magnetic properties can be par- tially reflected by the ratio of remnance, denoted as (Mr(E)-Mr(0))/ Mr(0), for both in-plane directions. Under a 17.8 kV/cm electric field, the ratios are about -54.9% and 23.3% for [100] and [011], respectively. The...
