Homework Help: Electric and magnetic fields

  1. Jan 24, 2004 #1
    Does the following equation mean that electric field E and magnetic field B are always perpendicular??
    the equation is:
    Curl E = - (partial derivative of B with respect to t)
    where E is time dependent too.

    [tex] \vec E \cdot \vec B = 0 [/tex]

    say's E & B are 90 degrees to each other.
