If you have magnetization vector in vertical magnetic field, it starts precessing. If you do a transformation to rotating coordinate system you obtain a stationary magnetization. Is there a direct formula to see that magnetic field is zero?
I understand that under transnational changes (e.g. motion along $x$) electric and magnetic field behave as: \begin{align} & E'_x = E_x & \qquad & B'_x = B_x \\ & E'_y = E_y - v B_z & & B'_y = B_y + \frac{v}{c^2} E_z \\ & E'_z = E_z + v B_y & & B'_z = B_z - \frac{v}{c^2} E_y . \\ \end{align} The easyest way to derive it is to consider Lorentz transformation of the $A^\mu$ and take $\gamma \to 1$ limit.
Is there analogous formula for rotation?
This is the closest I found on SE but it doesn't answer my question.
