a, SrTiO3 unit cell in the absence of a terahertz electric field. When a circularly polarized terahertz field pulse drives a circular atomic motion, dynamical multiferroicity is expected to create a net magnetic moment in the unit cell. b,c, The north pole points up for a pulse that is le...
At the earth, the electric field strength in the polar cap is the voltage generated by the connection process divided by the size of the polar cap, roughly 5000km, yielding 10V/km or 10mV/m. From:The Earth’s Electric Field,2014
