Hi Antonio,

I see.  So if I have a charge ball, "I" won't see a magnetic field since I
am stationalry in relation to the charge.  However, if a person were flying
by us (me and the charge), they would pass trhough the E-fields and see a
magnetic field.  I never thought about that *:-)

Cheers,

	Terry
