## Homework Statement

Given the magnetic field intensity, H, find E.

H=[tex]\hat{y}[/tex]6cos(2z)sin((2x10^7)t - 0.1x)

## Homework Equations

[tex]\nabla[/tex] [tex]\times[/tex] E = [tex]\frac{- \partial B}{\partial t}[/tex]

## The Attempt at a Solution

Since we have H, we can use the relationship that [tex]\mu[/tex]H = B and then take the partial derivative of that with respect to time. That would give us this quantity...

[tex]\frac{- \partial B}{\partial t}[/tex]

Now, how do I get to E-field from that? How do you "uncurl" that?
