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.

Question 1: When an external magnetic flux through a conducting loop decreases in magnitude, a current is induced in the loop that creates its own magnetic flux through the loop. How does that induced magnetic flux affect the total magnetic flux through the loop? O It does not affect the total magnetic flux. O It decreases and then increases the total magnetic flux. OIt increases the total magnetic flux. OIt increases and then decreases the total magnetic flux. O It decreases the total magnetic flux. Part (a) Some additional information, which is not included in the video, is that the SI unit of magnetic flux is the weber, denoted Wb. Using that information and the contents of the video, solve this numerical problem: A conducting loop, with a resistance of 2.0 Q2, encloses magnetic flux that is increasing at the rate of 2.0 Wb/s.

Motional EMF Below is a rectangle that is being pulled into a magnetic field as shown. The rectangle has a height of h = 0.400 m and is being pulled to the right with a velocity of v = 188.0 m/s. This magnetic field starts where shown, so the left most side of the rectangle has no magnetic field. There is 1 loop with a total resistance of R = 15.40 Ohms. The magnetic field has a magnitude of B = 34.0 mT. That means as the loop moves to the right, the magnetic flux inside the loop is increasing.
