Consider C-14 and C-12 atoms that have been ionized once (i.e. each has had a single electron removed).     removed a single electron from each). They enter a mass spectrometer     spectrometer with a magnetic field of 0.75 T. If I want the     ions to be separated by 1mm after a 1/2-circle run, what should their     their speed? If the speed selector has a magnetic field      magnetic field of 0.2 T, what must its electric field be? By what     potentile difference have the ions been accelerated? If the speed selector     speed selector is made up of two plates spaced 2 mm apart (a bit like a capacitor)     capacitor), what should be the potential difference between the plates?

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.
