Near the surface of the earth, a magnet is made to levitate above another magnet, which is on a table, due only to magnetic force. The levitating magnet has a mass of 150 g with its north pole facing the magnet on the table and its south pole facing upwards. A stream of electrons is shot between the magnets, perpendicular to the field. Describe, in general, what will happen to the electrons, ignoring the effects of gravity on the electrons. Sketch the magnetic field between the two magnets.

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.
