An elastic conducting material is stretched into a circular ring and placed in a constant, uniform background magnetic field as shown below. Initially the conducting material is a circular ring of radius 0.08 m. When released at t=0 s, the ring begins to shrink. After 0.5 s have passed, the ring has shrunk to a new radius of 0.03 m.  (a) What is the change in the ring’s area from t=0 to t=0.5 s?  (b) If the constant, uniform background magnetic field has a strength of  0.8 T, what is the change in magnetic flux (∆ΦB) through the ring?  (c) What is the magnitude of the induced EMF in the ring?

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.
