Problem 3.363

Using Eqs. \((3.6 \mathrm{~h})\), demonstrate that if in the inertial reference frame \(K\) there is only electric or only magnetic field, in any other inertial frame \(K^{\prime}\) both electric and magnetic fields will coexist simultaneously, with \(\mathbf{E}^{\prime} \perp \mathbf{B}^{\prime}\)
