In a cathode ray oscilloscope, 100 electrons are moving with a speed of 8.0 x106 m/s horizontally and passes through the neck tube coils which creates a magnetic field of 25 mT. If It experiences a magnetic force of 2.8 X10-14 N, how can you predict the angle of motion of charges? If the charges are stationary, can the field produce magnetic force on these charges? If these charges are moving in an electric field, can it produce a force? Justify your answer for both cases. (Charge of electron=1.6 x 10-19 C.)

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.
