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.

A bubble chamber is a vessel with a uniform magnetic field running through it filled with a superheated transparent liquid (most often liquid hydrogen) used to detect electrically charged particles moving through it. It was invented in 1952 by Donald A. Glaser, for which he was awarded the 1960 Nobel Prize in Physics. Here is a photograph obtained in a bubble chamber, showing various charges circling around because of the magnetic field: Which of the following statements is false? Hint: Use the formula you found in the last question to help you with this question. Particles with positive charge will circle in one direction (perhaps clockwise) while particles of negative charge will circle in the opposite direction (perhaps counterclockwise). Heavier charges would have a larger radius of curvature, Particles with a larger charge would have a larger radius of curvature. Faster particles would have a larger radius of curvature.
