Problem related to electric and magnetic energy densities

1. Homework Statement

How can be shown that the electric energy density is completely dominated by the magnetic energy density for non-relativistic plasmas?

2. Homework Equations

the electric energy density is given by [tex]{\epsilon_{0}.E^{2}}{}[/tex], and the magnetic energy density is given by [tex]\frac{B^{2}}{2\mu_{0}}[/tex]

3. The Attempt at a Solution

To relate the magnitude of the two fields it should be used one of the Maxwell's eqs, i.e.:
[tex]\nabla[/tex][tex]\times\vec{E}[/tex] = -[tex]\frac{d\vec{B}}{dt}[/tex]

But this is all I can do so far...:confused:
Please , help me with a hint how to use the given ..

Thank you in advance
