27.20     Cyclotrons are widely used in nuclear medicine for producing short-lived radioactive isotopes.  These cyclotrons typically accelerate H− (the hydride ion, which has one proton and two electrons) to an energy of 5 MeV to 20 MeV.  This ion has a mass very close to that of a proton because the electron mass is negligible—about 1/2000 of the proton’s mass.  A typical magnetic field in such cyclotrons is 1.9 T.  (a) What is the speed of a 5.0-MeV H−?  (b) If the H− has energy 5.0 MeV and B = 1.9 T, what is the radius of this ion’s circular orbit?

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.
