ElectroMagnetism

Figure shows a coil of conductor carrying in clockwise direction. The point P is marked at a distance x from the center of the coil and it is desired to find strength at the point due to current carried by the coil. Let ds and ds’ be elements of the conductor and the distance of … Read more

Figure 1 shows a straight solid conductor in which the steady current I is flowing in upwards direction. The magnetic flux is produced due to current flowing in the conductor. The magnetic flux is produced outside the conductor along its complete length. The flux lines are in one plane and are perpendicular to the direction … Read more

If a compass is brought near a electric current carrying conductor, needle deflects which shows the presence of magnetic field around conductor. It has been observed that magnetic flux exists in circles around the conductor as shown in figure (c) and (d). The direction of current in the conductor and direction of field produced is … Read more
