Suppose you have a coil with 200 turns. You take a bar magnet and move it towards the coil over the course of 1.2 seconds, within that time , the magnetic field which is parallel to the normal of the surface area, increased by .844 T. If the area of one coil is .05 m^2, determine the induced electromotive force in the coils from the changing magnetic Field. ( simply give magnitude, no need for minus sign)

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.
