Interaction of Small Particles with Electric and Electromagnetic Fields
A small particle consists of many atoms, which provide its strong interaction with external fields. In electric fields, a dipole moment is induced on a small particle, and its value is proportional to the particle’s volume, or to the number of atoms that constitute the particle. Because a small particle consists of a large number of atoms, an induced electric dipole moment of the particle may not be small even at low electric fields. This determines the particle’s behavior in a plasma and the interaction between small particles located in external fields. Below we evaluate the electric parameters of small particles under various conditions.
