A particle of mass "M" and charge "+Q" Travels at a velocity "V" in a plane perpendicular to a Magnetic Field of magnitude "B" as shown in the Picture. The particle will experience motion on a circular path. a. What is the plane of the circular path? (XY, XZ or YZ) Explain why. b. Start with Newton's 2nd law and find the Radius of the circular path. c. Is the particle moving clockwise or counterclockwise? Explain. d. Find the time it will take to complete one full revolution if the particle is a proton traveling at 0.1% the speed of light, in a 0.5 T magnetic field Assume similar conditions as problem 1 but now the proton, moves along the magnetic field undeflected. This new behavior can only be explained if there exist an external electric field in addition to the magnetic field. What is the magnitude and direction of such field? (you can disregard gravity)

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.
