Electric field and magnetic field relationship

  1. Jul 8, 2007 #1
    We find in the literature the following relationships between electric field E and magnetic field B
    Is there a way to define the situations when they hold?

    apparently only if v^2=c^2 for nonzero fields

    Your first expression is the relation between B and E for a charged particle moving in the x direction.
    Your second expression is for a different situation.It gives the relation between
    E'_y and B'_z if you are moving with velocity v in the x direction with respect to a pure magnetic field (no E) B_z.

    E and B

    thanks. is there a special name for E' in the second case?

    E and B relationship

    Consider please the equation
    If I call E=F/q E has that E a special name?
