  The T-odd phenomenon of induction of the magnetic field by a static electric
field provides to study the electron EDM and constants of T-odd, P-odd
interaction of an electron with a nucleus. Measurement of this magnetic field
for ferroelectric materials (like PbTiO_3) at the level B~3 10^{-18} G allows
to derive the electric dipole moment of an electron at the level d_e ~ 10^{-30}
e cm and the constant of T-odd scalar weak interaction of an electron with a
nucleus at the level k_1^{nuc}10^{-9}. The atomic magnetometry makes possible
to measure fields ~ 10^{-13} G/\sqrt{Hz} now. This means that for 10 days
operation one can expect to obtain B at the level B ~ 10^{-16}G, and,
therefore, the limits for d_e in PbTiO_3 at the level d_e ~ 10^{-28} and
k_1^{nuc}~10^{-7}. that makes the discussed method beneficial for measuring d_e
and k_1^{nuc}.
