Calculate the magnetic force on a current-carrying conductor. Because charges ordinarily cannot escape a conductor, the magnetic force on charges moving in a conductor is transmitted to the conductor itself. Figure 1. The magnetic field exerts a force on a current-carrying wire in a direction g...
Measuring the magnetic force on a current-carrying conductor.Presents an efficient method for the measurement of the magnetic force acting on a current-carrying conductor, which uses an ordinary digital balance. Method; Results.HerremanW.Huysentruyt...
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...
Magnetic fields exert forces on moving electric charges. Changing magnetic fields in the presence of electric charges cause electrons to flow In 1820, Danish physicist Hans Oersted noted that electron flow produces a magnetic field. He had a current-carrying conductor pointing in a north-south dir...
conductor or the direction of velocity of positive charge is represented by the linear motion of the screw motion, then the direction of the magnetic field can be represented by the direction of rotation of the screw. (b) Right hand claps rule: If a current carrying conductor is clapsed...
