Part A You and a friend get lost while hiking, so your friend pulls out a magnetic compass to get reoriented. However, you're standing right under a power line carrying 1.5 kA toward magnetic north; it's 10 m above the compass. The horizontal component of Earth's magnetic field at your latitude points northward and has magnitude 24 µT. Find the magnitude of the magnetic field induced by the power line at your location. Express your answer with the appropriate units. By = 30 µT Submit Previous Answers Correct Part B Find the total magnetic field at your location assuming that north is in the positive y-direction. Express your answer in microtesla in terms of the unit vectors i and j. || ? X.10" Brtal = 38.4i+0j µT O You have already submitted this answer. Enter a new answer. No credit lost. Try again.

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.
