Timeline for In electrodynamics, is the electric field always perpendicular to the magnetic field? if so, is there a simple way to prove this?

| Jan 28, 2018 at 15:07 | comment | added | Philip Wood | I focused on what I could understand – the clear and unambiguous question in your first paragraph. [I note that the other answers do the same.] | |
| Jan 28, 2018 at 14:52 | comment | added | Mahlomola Daniel Cwele | The key in your quote is "at all times". But, please do not focus on a single part of the question, as I went to some length to make sure that the question is as clear as possible. | |
| Jan 28, 2018 at 14:38 | comment | added | Philip Wood | With respect, your question (as worded at the time I answered it) asked "can one argue that E⃗ ⊥B⃗ at all times?" A single exception to E⃗ ⊥B⃗ is enough to show that one $can't$ uphold the claim. | |
| Jan 28, 2018 at 14:33 | comment | added | Mahlomola Daniel Cwele | It seems that you are interested in finding an isolated example. As the question clearly shows, the interest is in whether this kind of conclusion would hold IN GENERAL, and for ALL SUCH SOURCES, not just for an isolated example. in fact, I have already provided an example under which the magnetic and electric field are known to be perpendicular, thereby stressing that this not the problem with which I need help. | |
