You are lost in the woods!  But you happen to have a magnetic field sensor with you.  This sensor will tell you the direction of the Earth's magnetic field where you are.  This is NOT a compass, but an actual device for measuring magnetic field.  You know that you need to travel North (geographically) to reach the nearest town. Your sensor tells you that the magnetic field is pointing to your right. Which direction should you travel in order to go to the geographic North?  Make sure to think about directions of magnetic field vs. the geographic directions.

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.
