N2  - Within general nonlinear electrodynamics given
by a local action, very special magnetic field configuration
 carrying no magnetic charge is found as a linear response
 of the vacuum, filled with constant electric and magnetic
 fields, to an embedded static electric charge. When the electric
 charge is point-like and external fields are parallel, the
 response found may be interpreted as a field of two point-like
 magnetic charges of opposite polarities in one point. Coefficients
 characterizing the magnetic response and induced
 current are specialized to quantum electrodynamics (QED),
 where the nonlinearity is taken as that determined by the
 local Heisenberg–Euler effective action. It is demonstrated
 how the same response is reproduced in the (nonisotropic)
 region remote from the charge by considering the polarization
 operator of QED
