Getting E-Field from magnetic field intensity, H

  • #1

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?

You could use Stokes's theorem to "uncurl" E. Do you see where it's headed?

Also, just to help you out in the future, anything with Calc 3 doesn't really belong in intro physics, and you may be helped quicker in advanced physics for questions like this.
