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 ...
DC Motor Operation: The force acting on a current-carrying conductor in a magnetic field explains the rotation mechanism of a DC motor. Oersted discovered that a compass needle deflects near a current-carryingconductor, showing it exerts a force on the needle. In 1821, Faraday found that a c...
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...
