comment Computing the Poynting vector?
It ended up being $S_z = -\frac{ c}{ \mu_0}(B_x^2 + B_y^2)$, a negative, and I do not understand why? How does the cross product work out... What I am I interpreting incorrect in the following: $\vec E = [c B_x, cB_y, 0], \vec B = [B_x, B_y, 0]$ and $\vec E \times \vec B = i(c B_y \cdot 0 - 0 \cdot B_y) - j(c B_x \cdot 0 - 0 \cdot B_x) + k(c B_x \cdot B_y - B_x \cdot B_y) = 0$ ?

How do I approach computing $E$, at $x = 0, y = 0, z = 0, t = 0$, wouldn't $B = B_x + B_y$, hence $E = c(B_x + B_y)$? (using this value doesn't give me the correct result)

Your answer definitely make way more sense!

Also on the note of the $sigma$, the answer was given as $\sigma_{final} - \sigma_{initial} = 69.3$

Sorry, I have a bad tendency to see what I wanted to write rather than what I actually wrote (I went ahead and updated the other question) and I am not particularly framilar with conventions for greek letters in physics. Please leme know if other changes are needed.
