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.

Hall potentials are much larger for poor conductors than for good conductors. Why?
The immediate cause of many deaths is ventricular fibrillation, an uncoordinated quivering of the heart, as opposed to proper beating. An electric shock to the chest can cause momentary paralysis of the heart muscle, after which the heart will sometimes start organized beating again. A defibrillator is a device that applies a strong electric shock to the chest over a time of a few milliseconds. The device contains a capacitor of a few microfarads, charged to several thousand volts. Electrodes called paddles, about 8 cm across and coated with conducting paste, are held against the chest on both sides of the heart. Their handles are insulated to prevent injury to the operator, who calls Clear! and pushes a button on one paddle to discharge the capacitor through the patient's chest Assume an energy of 3.00 102 W s is to be delivered from a 30.0-F capacitor. To what potential difference must it be charged?
What Hall voltage is produced by a 0.200T field applied across a 2.60-cm-diameter aorta when blood velocity is 60.0 cm/s?
A solenoid 10.0 cm in diameter and 75.0 cm long is made from copper wire of diameter 0.100 cm, with very thin insulation. The wire is wound onto a cardboard tube in a single layer, with adjacent turns touching each other. What power must be delivered to the solenoid if it is to produce a field of 8.00 mT at its center?

Consider positive and negative charges all moving horizontally with the same speed through the four regions in Figure 17.2.

1: 1: A mass spectrometer is being used to separate common oxygen-16 from the much rarer oxygen-18, taken from a sample of old glacial ice. (The relative abundance of these oxygen isotopes is related to climatic temperature at the time the ice was deposited.) The ratio of the masses of these two ions is 16 to 18, the mass of oxygen-16 is 2.66 ✕ 10−26 kg, and they are singly charged and travel at 7.50 ✕ 106 m/s in a 2.00 T magnetic field. What is the separation (in m) between their paths when they hit a target after traversing a semicircle? _______m (resubmitting question, 0.0778m is an incorrect answer)

Two isotopes of carbon, C-12 and C-13, have masses of 19.92 x 10 -27 kg and21.59 x 10 -27 kg, respectively. These two isotopes are singly ionized (due tothe removal of one electron) and each is given a speed of 6.667 x10 5 m/s. The ions then enter the bending region of a mass spectrometer where themagnetic field is 0.8500 T. Determine the spatial separation (differencebetween the diameters of the trajectories) between the two isotopes after they have traveled through a half-circle.
