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.

An electrocardiogram (ECG) measures electric activity of neurons in the brain. Electroencephalograms and electromyograms respectively measure similar activity over the scalp and over the skin surrounding muscle cells. Because the electrical activity of the human body varies with time, the time-varying electric fields in the body lead to the generation of magnetic fields that can then be measured. The magnetocardiogram, developed in the 1960s, was the first such device. More recently, superconducting quantum interference devices (SQUIDS) have been used for these measurements. One important application of this technique is the monitoring of the fetal heart by measuring the magnetic field produced by currents in the heart at the surface of the mother's abdomen. The fetal heart at 28 weeks gestation can be modeled as a single-loop coil 1.50 cm in diameter, oriented so that the plane of the loop is parallel to the abdominal surface of the mother, and a magnetic field of 10.0 pT is typically…
