Magnetic Field Of Coaxial Cable

The word coaxial means same axis. So for a long straight cable to be coaxial, it must have concentric cylindrical shaped conductor around it. Coaxial cable (popularly called ‘coax’) has various applications ranging from current conductors to radiofrequency signal transmitters. This cable has lower emission losses and provides protection from electromagnetic interference which allows signals with less power to transmit over longer distances.For example, currents produced in the pickup of a stereo turntable generally travel to the amplifier through a coaxial cable.The self-inductance of a coaxial cable is another important characteristic, because it influences the propagation of electrical signals in the cable.

Figure 1: CRT with coils in Helmholtz configuration. The hot cathode emits electrons which are then accelerated through potential difference Vacc. When the electrons enter the magnetic field B, which is perpendicular to their velocity, they move on a circular path with radius r. The magnetic field is due to coils in Helmholtz configuration (2 coils separated distance that equals their radius). The magnetic field due to one of the coils with radius R, at a point on the axis distance z away from the center of the coil, was found using the Biot-Savart law: HOIR?N B1 2(R2 + z2)ž
