  Hadron decay widths are shown to increase in strong magnetic fields as
$\Gamma (eB) \sim \frac{eB}{\kappa} \Gamma(0)$. The same mechanism is shown to
be present in the production of the sea quark pair inside the confining string,
which decreases the string tension with the growing $eB$ parallel to the string
. On the other hand, the average energy of the $q\bar q$ holes in the string
world sheet increases, when the direction of $\mathbf{B}$ is perpendicular to
the sheet. These two effects stipulate the spectacular picture of the
$\mathbf{B}$ dependent confinement and $\alpha_s$, discovered on the lattice.
