- a) The second of Maxwell's equations states that the divergence of the magnetic flux density is always zero, i.e. V B 0. What does this tell you generally about the distribution of magnetic flux? Describe the impact of a non-zero value on the right-hand-side of Maxwell's second equation. b) With reference to Figure 2, the Biot-Savart law can be used to show that the magnetic flux density due to a straight current-carrying wire of finite length is given by Hol %3D (cos a2 - cos a,) âg 477 Figure 2 Show that this expression is consistent with Ampère's law when applied to a long straight current carrying conductor. c) Figure 3 depicts a section of printed circuit carrying a current / of (100 + 10X) mA.

Use the Lorenz coordinate transformation c2 at2 and find the wave equation in frame S' that moves with the velocity of u with respect to S.Q5. Consider the Nyquist plot of the frequency response of the open-loop system 10000 G.(s) (s+ 1)(s+10)(s + 50) which is shown in Figure Q5 below.
