This work is based on the variational principle for magnetic field lines introduced in 1983 by Cary and Littlejohn. The action principles for magnetic fiel
The magnetic North Pole is the location in theNorthern Hemispherewhere the planet's magnetic field lines point straight downwards, penetrating the surface of the Earth. Its location changes at a rate of about 56 kilometers (35 miles) per year. Currently, it is located in the Arctic Ocean nor...
Magnetic-field exposure is typically associated with microwave ovens, power lines, vacuum cleaners, and hair dryers. From The Daily Beast This magnetic field can be increased in value, without increasing the current in the conductor, by adding more turns to the coil. From Project Gutenberg The ...
magnetic pole- either of two points where the lines of force of the Earth's magnetic field are vertical geographic point,geographical point- a point on the surface of the Earth 2. magnetic pole- one of the two ends of a magnet where the magnetism seems to be concentrated ...
The magnetic field midpoint of the plasma flow Mach number was set to 1. The default magnetic field was produced by the single current, and under the condition of this specific field configuration, the plasma density distribution for different magnetic field intensities (as shown in Fig. 4a) ...
1. A theoretical spine and fan field structure is shown in Fig. 1A, B, where the spine fields coming toward the null point (black dot in the middle) diverge out to infinity on the xy-plane to form the fan surface. In the sun, however, we can see only the field lines rooted in ...
25-2 Magnetic field 物理学是整个自然科学和现代工程技术的基础。英文版大学物理课程的开设,首先是使学生掌握专业所必须的物理基础知识和专业词汇;进而要让学生对物理学的内容和方法、工作语言、概念和物理图像,其历史、现状和前沿等方面,从整体上有个全面的了解。这是
Hence, this component of the electric field drives the particles in the x direction50,51. The interesting point is that a strong signal is seen in the presence of a guide field, i.e., when there is significant magnetic field pile-up. These particles are thus likely not accelerated during...
