Describe the magnetic field that exists between the plates of a charging or discharging capacitor with parallel circular plates. The magnetic field lines are straight lines perpendicular to the plates (ignoring fringing at the edges.) The magnetic field lines are straight lines parallel to the plates (ignoring fringing at the edges.) There is no magnetic field between the plates. The magnetic field lines are circles around an axis perpendicular to the plates (ignoring fringing at the edges.)

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.
