The aurora is caused when electrons and protons, moving in the earth's magnetic field of 5.00 × 10−5 T, collide with molecules of the atmosphere and cause them to glow. What is the radius of the circular orbit for a proton with speed 4.20 × 106 m/s, in meters? Assume that the electron moves in a plane perpendicular to the magnetic field. The mass of a proton is 1.67 × 10−27kg. Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. 2- diagram below

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.
