Tribo-electricity and friction. IV.—Electricity due to air-blown particles
Electric charges due to mutual impact of dust or other particles arise in various ways: ( a ) electric dust- or sand-storms in the Tropics; ( b ) electric snow storms in the Antarctic; ( c ) electric flashes seen in the ejectamenta from volcanoes; and ( d ) electric charges, and possibly sparking, b...
