In this paper, spectra of the quarkonium states has been studied using the conditions temperature, chemical potential and
the magnetic field. Here our main focus is to study the effect of strong magnetic field on the quarkonium properties. The
binding energies and the dissociation temperature for the ground and the first excited states of the charmonium and
bottomonium in the presence of strong magnetic field at chemical potential μ = 500 MeV has been studied. Here we use
quasiparticle(QP) Debye mass depending upon temperature, magnetic field and chemical potential obtained from the
quasiparticle approach. The Debye mass strongly increases at different values of temperature and magnetic field. The binding
energy decreases with increase in the temperature at different magnetic field eB=0.3, 0.5, and 0.7 GeV2 and also decreases with
magnetic field at different at T=200,300 and 400 MeV for the J/ψ, Ψ’, ϒ, and ϒ’ states of the quarkonia. The dissociation
temperature of the quarkonium states falls with the increasing values of the magnetic field at critical temperature Tc =197 MeV.
