Homework Help: Electric n magnetic field vectors

  1. Sep 13, 2005 #1
    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 [itex]\partial\vec{E}/\partial{t}[/itex].

    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.

    In the case of a plane wave you can find B if you know the direction of propagation.
