50. Calculate magnetic and electric field when:
\textbf{A}^{(2m)}(x) = \frac{\textbf{m}(t - r) \times \hat{x}}{4\pi r^2} + \frac{\dot{\textbf{m}}(t - r) \times \hat{x}}{4\pi r}
When is given:
\textbf{E} = -\nabla A^0 - \dot{\textbf{A}}
\textbf{H} = \nabla \times \textbf{A},
\textbf{m}(t) = \frac{1}{2} \int_{\mathbb{R}^3} \textbf{y} \times \textbf{j}(t, \textbf{y}) d^3y,
Pls make as many intermediate steps as possible!
