# Electric n magnetic field vectors

benitta
what is the relation between the electric and magnetic field ?
if the electric field vector is e = E exp[i(kx-wt)]j what is the magnetic field vector?

Hi benitta,

I don't believe there is such a relation.

However, the maxwell equations tell us that there is a magnetic field associated with a change in electric field $\partial\vec{E}/\partial{t}$.

All you need to do is solve Maxwell's equations. See

Hi again,

Sorry I misread your question and missed the "t term" in there.
