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.

a) What would happen to the magnetic field and the current if the direction of motion of the magnet is reversed? b) What would happen to the magnetic field and the current if the magnet is moved more quickly in the same direction? c) What would happen to the magnetic field and the current if the magnet is moved rapidly back and forth? My Answer: I attached my answer below as well as the drawing of the coil and magnet. I am just unsure as to whether my first to answers (a and b) are correct and then for c), what the affect on the magnetic field is. a) Current: If the direction of motion of the magnet was reversed then the direction of the current would also be reversed. Magnetic Field: Since the magnetic field in the coil wants to oppose the moving magnetic field, an induced magnetic field will be created that will attract the magnet and prevent it from moving away from the coil. b) Magnetic Field and Current: If the magnet moved more quickly in the same direction, then the…
