Supposed a non-uniform magnetic field was probed with a magnetometer giving values in terms of millitesla (mT). The values were plotted along a grid with area of 4 square meters per grid. You were ale to calculate for the total magnetic flux calculated for the probed area, which was 90 mWb. You were able to plot in a sample grid the individual values for magnetic fields you have probed. But in the process of preparing your data, you spilled coffee on your data sheet, erasing a single grid in your data. You were required to present all data yet you have no more access to the magnetometer and field already varied. The only way to present your data is to estimate and calculate backwards. What is the magnetic field value at cell x (in mT) if the values for the other grids are as follows?: 2 2 9 x

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.
