However, when implemented, this method failed to identify cavity/waveguide modes in the magnetic field data recorded by Active Magnetospheric Particle Tracer Explorers/CCE for events that showed pronounced field line resonances in the azimuthal (by) channel. An examination of data from a 3-D MHD ...

To simulate and obtain the magnetic field of a wire carrying current, the “magnetic field” module is used. Also to assign current characteristics to wire I have used “multi turn coil-linear”. We have considered wire length a finite number but the magnetic field of wire cor...
不少考生对托福听力中的天文学(astronomy)总是望而却步,这是为什么呢? 原因很简单,我们或多或少都上过生物、历史、艺术、音乐课,所以日积月累还是有些知识储备的。然而天文学在我们生活中出现的频率相对较低,导致我们积累的天文学知识较少,加上天文学相关词汇难度较大,这才使得同学们心生畏惧。
Directly proportional to the number of turns of the loop. This means N is proportional to I This happens because the current in each turn would be in the same direction. Hence, the field due to these adds up. Inversely proportional to the radius of the loop. ...
每日一词｜太阳磁场测量 magnetic field measurements of the sun 据中国科学家介绍，世界首台“用于太阳磁场精确测量的中红外观测系统”（简称AIMS望远镜）突破了太阳磁场测量难题，将矢量磁场测量精度提高一个量级。The world's first solar magnetic-field telescope (AIMS telescope) working in the mid-infrared ...
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
We attempt to establish the mathematical expression of the current and the magnetic field in a metallized capacitor. The expression of the impedance of this capacitor is also presented. The distribution of the current is discussed through the variation of the capacitor impedance and compared to exper...
