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.

At the equator, the earth's field is essentially horizontal; near the north
pole, it is nearly vertical. In between, the angle varies. As you move
farther north, the dip angle, the angle of the earth's field below
horizontal, steadily increases. Green turtles seem to use this dip angle
to determine their latitude. Suppose you are a researcher wanting to test

the magnetic field strength is 50 μT and the dip angle is 56°. You then

change the field by passing a current through a 100-turn horizontal coil
