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.

Question

Which of the following statements is TRUE about mapping magnetic field lines around a bar magnet
using a compass?
A. The experiment is wrong because the magnetic field being detected by the compass is the resultant
of the bar magnet's magnetic field and the Earth's magnetic field.
B. The magnetic field being detected by the compass is the resultant of the bar magnet's magnetic field
and the Earth's magnetic field.
C. The magnetic field near a bar magnet is very much larger compared to the Earth's magnetic field,
thus, the mapped magnetic field using a compass is indeed from the bar magnet only.
D. The magnetic field lines around a bar magnet are effectively estimated by the experiment because
the concrete walls isolate the inside of a laboratory or a house to the Earth's magnetic field.
E. The intensity of the bar magnet's magnetic field can be determined by the compass.
