Contribution

It introduces a mechanism for dipole moment generation in Born-Infeld electrodynamics and computes the polarizability coefficient.

Findings

Polarizability coefficient proportional to the cube of the characteristic length

Dipole moment can be induced by external fields in Born-Infeld theory

Physical implications of induced dipole moments are discussed

Abstract

The mechanism for the generation of a dipole moment due to an external field is presented for the Born-Infeld charged particle. The 'polarizability coefficient' is calculated: it is proportional to the third power of the characteristic length in the Born-Infeld theory. Some physical implications are briefly discussed.
