From IFPA wiki
  1. Convert 1 Tesla to natural units.
  2. Show that [math]\tilde F_{\mu\nu}F^{\mu\nu}[/math] can be rewritten as [math]\partial_\mu K^\mu[/math].
  3. What is the vector potential [math]A_\mu[/math] of a static charge at the origin in the axial gauge [math]A_0=V=0[/math] ?
  4. What is the expression of the energy density and of the momentum density of an electromagnetic field as a function of [math]\vec E[/math] and [math]\vec B[/math]?
