If a bar magnet is dropped through a conducting loop with its South pole downward as shown in the figure below, what is the direction of magnetic field passing through the loop produced by the bar magnet and what will happen to the magnetic flux (0) through the loop? Current meter S A. O increases, B-field by magnet is pointing downward. B. O increases, B-field by magnet is pointing upward. C. O decreases, B-field by magnet is pointing upward. D. O decreases, B-field by magnet is pointing downward. E. O is constant, B-field by magnet is pointing upward.

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 radiofrequen…
