In general it depends on your intertial frame what fields you see.<p>See for example: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Classical_electromagnetism_and_special_relativity#The_E_and_B_fields" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Classical_electromagnetism_and...</a> and <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Moving_magnet_and_conductor_problem" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Moving_magnet_and_conductor_pr...</a>
