EMFs do stir up mercury.
The higher the voltage, the higher the EMF. EMF induction occurs when voltage changes direction, such as in A/C voltages that are found in typical 120 volt house circuits.
CRT monitors have the same effect (stir up mercury) because of the high voltage alternating currents they contain in the flyback transformer which is connected to the CRT tube itself.
