I'm afraid there's no nuance at all Julia. The "mutual induction" explanation is wrong. E and B are in phase because they're space and time derivatives. See this answer where I used a canoe analogy.

There aren't really two different fields, there's one field, and two derivatives of it. Spatial and time.

That's not quite right because there's only one field there.

That's not quite right because there's only one field there. Electromagnetic field interactions typically result in linear and/or rotational force. When we only see linear force we typically talk of an E field, when we only see rotational motion we typically talk of a B field, but these result from F_μν field interactions.

This seems to be wrong...

There is no correct causal statement at all.

Shrug. There is no correct causal statement at all.
