•• Three long, parallel straight wires pass through the vertices of an equilateral triangle that has sides equal to 10 cm, as shown in Figure 27-53. A dot indicates that the direction of the cur- rent is out of the page and a cross indicates that the direction of the current is into the page. If each current is 15 A, find (a) the magnetic field at the location of the upper wire due to the currents in the two lower wires and (b) the force per unit length on the upper wire. 34 (X) 10 cm FIGURE 27 -53 Problems 34 and 35 10 cm 10 cm

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.
