Crop circle figures above are remarkably similar to magnetic field patterns, like in metal, ferromagnetic sawdust, or some PC simulations of electromagnetic fields. The lightning discharge works like a conductor, placed perpendicularly (not in every cases) to the ground.
Kufuatia mazao mduara takwimu ni inashangaza sawa na mwelekeo wa magnetic shamba, kama katika chuma machujo ya mbao, ferromagnetic. kutokwa umeme kazi kama kondakta, kuwekwa perpendicular chini, na shamba kubwa electromagnetic ameumbwa pembezoni zaidi mviringo, hivyo uwezo wa evoke introduktionsutbildning umeme katika masomo yote katika eneo hilo, ikiwa ni pamoja na mimea.
