ABSTRACT
The outer-ring electrons of dielectric materials do not move freely between molecules
,
but they will
escape from their exposed surfaces to satisfy an external electrical field. These materials also allow electric lines of force to pass through their mass to an electric field on the other side. These two phenomena are responsible for charge buildup on dielectric materials. There is always an exchange of electrons across the interface of dielectric webs in contact with each other or in contact with any guide material.
