A square coil of side 5 cm contains 100 turns and is oriented with its face perpendicular to a uniform 0.6 T magnetic field such that the field penetrates the coil which has a resistance of 100. The field drops to zero rapidly moving from inside the coil to outside. Moving perpendicular to B it is pulled at a constant velocity to the region where the field is zero. It takes 0.1 s to completely remove the coil from the field. (a) Find the EMF and current induced in the coil. (b) Calculate the force necessary to pull the coil from the fiel

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.
