Figure 1Magnetic field around a current-carrying conductor. The amount of current flowing through a single conductor determines the strength of the magnetic field it produces. Increasing the current flow increases the strength of the magnetic field. Normally the strength of the magnetic field around ...

The present work is aimed at calculating the magnetic field around a current-carrying conductor positioned in air at a given height above a two-layer ground. The method is based on the successive imaging technique. A three-phase transmission model was constructed to simulate three-phase transmissio...
Magnetic field C. Gravitational field D. Radiation field Correct Answer B. Magnetic field ExplanationMagnetic field is the area around a magnet. The magnetic field is the region around a magnet where the magnetic forces are observable. It is defined by the presence of magnetic force on mo...

Magnetic field around the solenoid axis 密绕螺线管除了沿轴主磁场外,还有一个被大家忽略的磁场分量,就是绕轴磁场。 之所以绕轴磁场不被大家注意,甚至全然不知,一是因为在一般应用场合完全可以不考虑绕轴磁场,再就是绕轴磁场分量相比于沿轴磁场分量而言是极其微弱的,不易被察觉。还有就是教科书上总把螺线管的磁场...
