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.

There are 2 thin uniform rods. Rod DC is pinned at its center of gravity (free to rotate 360 degrees), 6 FT long, and perfectly horizontal. Rod AB is perfectly vertical, pinned at the bottom of the rod and 6 FT long as well. Both pins are on the ground (So they form a perfectly horizontal line if you connect them). The pines are 9 FT away from each other. Rod AB is released from rest and hits the end of DC with a coefficient of restitution of 0.6 . DETERMINE THE ANGULAR VELOCITY OF BOTH RODS JUST AFTER IMPACT ASSUMING BOTH WEIGH 20 LBS EACH.
