Electromagnetism Problem (Using Electric field E to find D and B)

[keith river]

Given a propagating field expressed as E = Em Sin (wt - bz)j in free space, find the displacement (D) and the magnetic field (B) created by this electric field using a relevant maxwell's equation.

note : w is in fact omega
and b is beta.
j is a unit vector.


I dont know how I'm meant to solve this problem could someone post a step by step guide and say why each step is taken if you could. Thanks.

We don't do your homework for you here. You need to make (and show!) a reasonable attempt to get assistance.

As a starting point, the problem statement tells you to use the relevant Maxwell equation, so you might start by writing down Maxwell's equations and then figuring out which one(s) is relevant.:wink:
