A straight wire of length 25 cm sweeps across a 0.84 T magnetic field with a speed of 1.00 m/s. What is the maximum value of the electromotive force that can be induced in the wire? Given: L=25 cm=0.25 m B=0.84 T v=1.00 m/s Solution: The induced electromotive force is maximum if sin0 is equal to 1, that is, the angle 0 is 90°. Thus, the wire must move perpendicular to the magnetic field. Using Eq. (6.6), E = vBLsin90° = (1.00 m/s)(0.84 T)(0.25 m)(1) = 0.21 V. Practice Exercise 6.3 Suppose the wire in Sample Problem 6.3 is moving 60° with respect to the magnetic field. What is the magnitude of the induced electromotive force?

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.
