  We explore the physical consequences of a new nonlinear electrodynamics, for
which the electric field of a point-like charge is finite at the origin, as in
the well-known Born-Infeld electrodynamics. However, contrary to the latter, in
this new electrodynamics the phenomenon of birefringence and dichroism take
place in the presence of external magnetic fields. Subsequently we study the
interaction energy, within the framework of the gauge-invariant but
path-dependent variables formalism. Interestingly enough, the static potential
profile contains a linear potential leading to the confinement of static
charges.
