When Electromagnetic waves are polarised, does it filter out the vibrations in either the magnetic or electric field?

Electromagnetic waves travel as vibrations in the magnetic field and electric fields however since the magnetic field and electric field is perpendicular to each other, does this mean a polraised light ray will have vibrarions travelling in just one of the two fields?

• Both are filtered by the same factor. The ratio $E/B$ has to be constant to the speed of light. – Yuzuriha Inori Mar 11 '18 at 5:13

If you consider that the $\textbf{B}$ field is actually not a true vector but an axial vector then it is better to think of it as an anti-symmetric (or skew-symmetric) tensor that in 3 dimensions has only three non-zero components representing a plane of action in which the magnetic force acts on a current element lying in that plane the force being perpendicular to that current element. Looking at it from this point of view a linearly polarized EM wave has indeed its $\textbf{E}$ and $\textbf{B}$ fields oscillate in the same plane, the $\textbf{E}$ field as a line of action and the $\textbf{B}$ field as a plane of action. The plane of action was called by Ampere the "directive plane". This is why it is more revealing to index the field components not as $B_x,B_y,B_z$ but rather as $B_{yz}, B_{xz}, B_{xy}$.
