Abstract
The thermomagnetic behavior of quark-gluon plasma has recently received a lot of attention. In this work, we make use of the extended self-consistent quasiparticle model to study the thermodynamic properties of magnetized (2+1) flavor quark-gluon plasma. The system is considered as a non-interacting system of quasiparticles with masses depending on both temperature and magnetic field. This allows obtaining the equation of state of the system and the other thermodynamic properties such as the speed of sound. We use the extended self-consistent model to obtain the magnetization and show that QGP has a paramagnetic nature. In addition, we study the pressure anisotropy and calculate the transverse pressure. The obtained anisotropic pressure may be used in hydrodynamic studies of magnetized QGP produced in heavy-ion collisions. Finally, we examine the screening properties of magnetized QGP in the longitudinal direction by calculating the Debye screening mass.

Summary
Quark-gluon plasma (QGP), the state of matter believed to have existed shortly after the big bang, has been successfully created in high-energy collisions [1]. [45], we developed the extended self-consistent quasiparticle model and studied the behavior of energy density, longitudinal pressure, and entropy density of magnetized 2-flavor QGP. We apply the extended quasiparticle model to magnetized (2+1)-flavor QGP We use it to study the behavior of longitudinal pressure, speed of sound, magnetization, pressure anisotropy, and Debye screening. We go on to study the anisotropy between longitudinal and transverse pressures caused by the magnetization acquired by the system along the field direction. We study the behavior of the total longitudinal and transverse pressure, including the pure-field or Maxwell contributions.
