The Earth has an electric field. On average, this field points vertically downwards and it has a magnitude of about 100 N C-1 (Newtons per Coulomb). It exists because the Earth’s surface carries a negative charge of – 5 x 105 C, while the upper atmosphere carries a compensating positive charge. An average of 400,000 thunderstorms a day sustain a relatively constant electric field.
