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.

8.) Please refer to the diagram on page 41 of your course packet for the remaining questions. It's a sketch of the Bainbridge mass spectrometer, used to identify the masses of atomic isotopes. 8.) The velocity selector inside the central rectangle has a magnetic field pointing out of the paper with a field strength, B, of 0.380 T and an electric field of strength, E, of 122,000 N/C. With what speed will ions pass through the slit S2? Express you answer in exponential notation in m/s. Use the result as the speed of the ions in number 10. 10.) The element tin has ten stable forms; all have 50 protons, but the number of neutrons can vary from 62 to 74 (with not all numbers of neutrons forming stable isotopes). For an isotope of mass number 119, calculate the distance from the opening in slit S2 to where the ion would land on the photographic film, designated by 2r in the drawing, if the magnetic field B1 has strength of 3.20 T.

True or False. Write true if the statement is correct. If the statement is wrong, write false and correct discuss why it is wrong.1. There are FIVE (5) different magnetic types.2. For a current-carrying wire, the magnetic field produced is parallel to the wire.3. When using the right-hand rule, the thumb is pointing towards the direction of the charge.4. The right-hand rule is applicable to all charges.5. The curve inside a magnet is completed from North to South.
Use evidence and scientific reasoning to explain why the reading in the balance increased as Magnet 2 was lowered towards Magnet 1. Remember that Magnet 1’s North Pole was facing upwards while resting on the balance. In your response, be sure to describe the magnetic field interactions and the orientation of the magnetic poles for each magnet.
