5.2.5 Problems and solutions

The problems of this section use the generalised Ampère law and the constitutive relations of a simple medium,

together with Gauss's law $\nabla \cdot D={\rho }_v$. The constants are those of this book, ${\epsilon }_0=10^{-9}/(36\pi )=8.842\times 10^{-12}F/m$ and ${\mu }_0=4\pi \times 10^{-7}H/m$.
