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. We generally use a compass when its face is oriented parallel to the ground, consequently only picking up the horizontal component of the earth’s magnetic field. Say you were on planet X and feeling a magnetic field of 30.0μT horizontal to the surface of the planet. If you passed 480mA of current through on a current loop of diameter 20.0cm, how would you orient the loop so that your compass needle rotates 45 degrees. (Your compass face is level with the surface of the planet, and at the center of the loop.)

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.
