Description
It is important to understand the strong external magnetic field generated at the very beginning
of high energy nuclear collisions. We study the effect of the magnetic field on the anisotropic
charmonium formation in Pb+Pb collisions at the LHC energy. The time dependent Schrodinger
equation is employed to describe the motion of $c\bar{c}$ pairs. We compare our model prediction of the
non-collective anisotropic parameter v2 of $J/\psi$ with CMS data at high transverse momentum. This
is the first attempt to measure the strong magnetic field at the very initial stage of high energy
nuclear collisions.
