Induced Electric Fields: Exploring Gauss' & Lenz's Laws

[QUOTE="lighhhtworks, post: 4951726, member: 536145"] In electrostatics, [B]∇[/B] × [B]E[/B] = 0 so [B]E[/B] that is a conservative field and there must be sources of[B] E[/B] from which [B]E[/B] flows. We know that this sources are the electrical charges given by Gauss' Law. But when [B]B[/B] changes in time, [B]∇[/B] × [B]E[/B] = - ∂ [B]B[/B] / ∂t. Now the Gauss' Law no longer applies and if there are not net charges anywhere, there are no sources of [B]E[/B], so [B]∇ ⋅ E[/B] = 0. So how are the lines of an induced [B]E[/B]? Are they like [B]B[/B] lines in magnetostatics? They just "turn" around something and they don't have any start or end? And if they are, since Lenz's Law says that ε = [B]- [/B]∂φ / ∂t, are the lines of this [B]E[/B] induced exactly the opposite of the [B]B[/B] that induces it? Please let me know if I'm not making my self clear, my english is not that good. Thanks in advance! [/QUOTE]
