Maxwell's Equations   [12 marks]

Match up the names on the left and the principles on the right with the equations in the middle. (For each match, draw a connecting line.) Circle all that refer to Maxwell's equations.

Definitions:   $\vec{\mbox{\boldmath$D$\unboldmath }} \equiv \epsilon \vec{\mbox{\boldmath$E$\unboldmath }}$ $\epsilon \equiv \kappa \epsilon_\circ$ $\kappa$ = dielectric constant.
       
  $\vec{\mbox{\boldmath$B$\unboldmath }} \equiv \mu \vec{\mbox{\boldmath$H$\unboldmath }}$   $\mu = \mu_\circ (1 + \chi_m)$   $\chi_m$ = magnetic susceptibility.
       

(In vacuum, $\kappa = 1$ and $\chi_m = 0$.)
