Exercise 3. (12p) (Lorentz boosts) The Maxwell equations (7) are invariant under Lorentz transformations. This implies that given a solution of the Maxwell equa- tions, we obtain another solution by performing a Lorentz transformation to the solution. A particular Lorentz transformation is a Lorentz boost with velocity v in - direction and acts on the electric and magnetic field strength...
