An electron traveling from the sun as part of the solar windstrikes the earth’s magnetosphere at latitude 80.0° N in a region wherethe magnetic field has a strength of 15.0 mT and is directed toward theearth’s center. The electron has a speed of 400 km/s and is directed towardthe earth’s axis parallel to the equator. Magnetic forces send theelectron on a helical trajectory. This electron strikes the ionosphere, where it is furtheraccelerated by an electric field with strength 20.0 mV/m directednorthward parallel to the earth’s surface. What is the electron’s newspeed after it has been deflected 100 km southward by this field?

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.
