To monitor the breathing of a hospital patient, a thin belt is girded around the patient's chest as in the figure below. The belt is a 195-turn coil. When the patient inhales, the area encircled by the coil increases by 45.0 cm2. The magnitude of Earth's magnetic field is 50.0 ?T and makes an angle of 27.0° with the plane of the coil. Assuming a patient takes 1.50 s to inhale, find the magnitude of the average induced emf in the coil during that time.   ____?V

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.
