A long wire and coil are located in one plane, and a current of 4 amps passes through the wire, and a current of 10 amps passes through the coil. If the coil is in the form of a rectangle, its dimensions are 20 cm x 10 cm and the number of turns is 40 and the nearest long side to it is 10 cm away from the wire, then it is the applied force. On one of the two short legs by the long wire she is

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.
