An add-on question: can you somehow add some E externally (in phase with the E of the EM wave) and make E/B more than the current value of c (or similarly decrease B)?

Also, shouldn't the equation read: limit(say over spatial coordinates tending to the point where we are noting our observation of the ratio) E/B = c ? (because they are points where E and B are zero)

When a current-carrying conductor is placed in a magnetic field the wire experiences a force due to the interaction between the field and the magnetic fieldproduced by the moving charges in the wire. ... That iswhy the conductor experiences a force.A current carrying conductor placed in a magnetic field experiences a force. If the direction of the fieldand that of current are mutually perpendicular to each other, then the force acting on the conductor will beperpendicular to both and that can be determined using the Fleming's left-hand rule.
