Description
The hot QCD matter produced in any heavy ion collision with a nonzero impact
parameter is produced within a strong magnetic field.
We study the imprint that these fields leave on the azimuthal distributions and
correlations of the produced charged hadrons.
The magnetic field is time-dependent and the medium is expanding, which leads to the induction of
charged currents due to the combination of Faraday and Hall effects. We find that these currents
result in a charge-dependent
directed flow $v_1$ that is odd in rapidity and odd under charge exchange.
It can be detected by measuring
correlations between the directed flow of charged hadrons at different rapidities,
$\langle v_1^\pm (y_1) v_1^\pm (y_2) \rangle$
