摘　　要：Although heavy-ion collisions generate strong magnetic fields,their direct measurement is a challenging task.A new observable,the baryon electric charge correlation,was recently found to be sensitive to the magnetic field strength and thus could be used as a magnetometer for heavy-ion collisions.Additionally,this observable may shed light on the equation of state and phase structure of quantum chromodynamics(QCD)under magnetic fields.Determining and understanding the phase structure of quantum chromodynamics(QCD)is important in contemporary physics[1].
