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.

An infinite rectangular slab of thickness 2d is situated parallel to the x-y plane, with its center at z = 0. Its upper surface is situated at z = d, and its lower surface is at z = -d. The material is uniformly magnetized given by M = Moi, and there are no free currents everywhere. Solve for the magnetic field outside and inside the slab. Verify this by relating it to the auxiliary field given by Ā 1B-M. μο Hint: There is no magnetization outside the slab.
A current I is passed through a wire. A second wire of length L is moving perpendicular to the magnetic field generated by the first wire (see sketch below) with velocity v at a distance d. Write down the expression for the potential difference V between the ends of the moving wire. Consider the magnetic field B to be constant over the range of motion of the second wire (i.e. d » 1). Use μ for the vacuum permittivity. Please use appropriate algebraic symbols for multiplication (* for a × b), division (/ for a/b), exponents (a^b for a³), square root (sqrt(a*b/c) for √a× b/c) etc. For Greek letters use their names e.g. "theta", "alpha", "pi", "mu" (without the quotes) and for trigonometric functions use "cos", "tan", "sin" (without the quotes).
