Just to clarify this.
	EMF =
	 ElectroMagnetic Field and
	 ElectroMotive Force (electric potential)
	ELF = Extremely Low Frequency (0-300 Hz)
	EF = Electric Field (the 'E' field)
	MF = Magnetic Field (the 'M' field)

I would agree for the EF. It may reach MV/meter.
I would disagree for the MF. Discharging a capacitor in msec produces high currents, 
and high MF (for msecs). I would like discussion on this.
