Dear Physics Forums readers(adsbygoogle = window.adsbygoogle || []).push({});

Let a two dimensional rectangle R1 carry a surface charge [itex]\sigma[/itex] and be placed next to another rectangle R2 of the same shape made from metal (i.e. a conductor). What does the electric field look like close to the second rectangle?

My intuition would tell me, the field lines terminate on the close side of R2, causing accumulation of negative charge on the side close to R1 and positive charge on the far side which in turn emits a field. The net field could be seen as reaching through R2.

I tried to verify this using a finite element simulator and obtained the following image for the field (R1 left, R2 right):

Now it seems to me as if the field goes around the metal. Is that correct? Or can the field only terminate *on* opposite charges?
