1. The problem statement, all variables and given/known data
How can be shown that the electric energy density is completely dominated by the magnetic energy density for non-relativistic plasmas?
2. Relevant equations
the electric energy density is given by {\epsilon_{0}.E^{2}}{}, and the magnetic energy density is given by \frac{B^{2}}{2\mu_{0}}
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.:
\nabla\times\vec{E} = -\frac{d\vec{B}}{dt}
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
