  We show that a strongly correlated Fermi system with the fermion condensate,
which exhibits strong deviations from Landau Fermi liquid behavior, is driven
into the Landau Fermi liquid by applying a small magnetic field $B$ at
temperature T=0. This field-induced Landau Fermi liquid behavior provides the
constancy of the Kadowaki-Woods ratio. A reentrance into the strongly
correlated regime is observed if the magnetic field $B$ decreases to zero, then
the effective mass $M^*$ diverges as $M^*\propto 1/\sqrt{B}$. At finite
temperatures, the strongly correlated regime is restored at some temperature
$T^*\propto\sqrt{B}$. This behavior is of general form and takes place in both
three dimensional and two dimensional strongly correlated systems. We
demonstrate that the observed $1/\sqrt{B}$ divergence of the effective mass and
other specific features of heavy-fermion metals are accounted for by our
consideration.
