The direction of the magnetic field around a current - carrying conductor can be determined by _. A. Ohm's law B. Ampere's right - hand rule C. Coulomb's law D. Faraday's law 相关知识点: 试题来源: 解析 B。解析:安培右手定则可以用来确定载流导体周围磁场的方向。A选项欧姆定律是关于...
The obtained results demonstrate that the intensity of the magnetic field and electric current profoundly affects the vibration behavior of the plates. Through these effects, loss of energy will happen in the plate which in turn results in a decrease in the oscillation...

Figure 1. The magnetic field exerts a force on a current-carrying wire in a direction given by the right hand rule 1 (the same direction as that on the individual moving charges). This force can easily be large enough to move the wire, since typical currents consist of very large number...
A compass can be used to reveal both the presence and direction of this magnetic field, as illustrated inFigure 2. When the compass is brought close to a conductor carrying DC current, the north-seeking pole of the compass needle will point in the direction the magnetic lines of force are...
Oersted discovered that a compass needle deflects near a current-carrying conductor, showing it exerts a force on the needle. In 1821, Faraday found that a current-carrying conductor also deflects in a magnetic field, indicating mutual forces between the
Since a current carrying conductor has an associated magnetic fieldwith it.it就是指代current carrying conductor.这样就清楚了吧? 因为载流导体本身就含有相关联的磁场. (这个翻译不是很确定,因为不是很清楚这方面的专业知识,不过意思差不多是这样的)
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...
