Abstract
Heavy-ion collisions generate a huge magnetic field of the order of
1018 G for the duration of about 0.2 fm/c. This time may become an
order of magnitude longer if the electrical conductivity of quark matter
is large. We calculate the conductivity in the regime of high density and show
that contrary to naive expectations it only weakly depends on the MF.
