An astronaut is connected to her spacecraft by a25-m-long tether cord as she and the spacecraft orbit Earth ina circular path at a speed of 3.0 x 103 m/s. At one instant, thevoltage measured between the ends of a wire embedded in thecord is measured to be 0.45 V. Assume the long dimension ofthe cord is perpendicular to the vertical component of Earth’smagnetic field at that instant. (a) What is the magnitude of thevertical component of Earth’s field at this location? (b) Doesthe measured voltage change as the system moves from onelocation to another? Explain.

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.
