Induction charging mechanism
From AMS Glossary
induction charging mechanism
A physical process for particle charging involving the collision of pairs of particles in an ambient electric field.
Electric charge induced on the particle surfaces by the ambient electric field is made available for transfer when the two particles come into contact. Subsequent differential particle motions under gravity are postulated to result in large-scale charge separation. The specific role of specific charging in the electrification of thunderclouds has not been resolved.
