In Figure P19.46, the current in the long, straight ( wire is I1 8.00 A, and the wire lies in the plane of the rectangular loop, which carries 14.00 A. The dimensions are c = 0.20 m, a 0.30 m, and I = 0.70 m. Find the magnitude and direction of the net force exerted by the magnetic field due to the straight wire on the loop.(Take positive if the net force is to the right.)

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.
