The production of electron-positron pairs due to accelerated electrons in a magnetized plasma is considered. The high-energy electrons are produced during laser-plasma interactions in the presence of spontaneously produced magnetic fields. By using a classical fluid description, we analyze the generation of electrostatic wakefields at the plasma wave-breaking limit and estimate the number of produced pairs for different situations. We note that in some cases, the presence of the magnetic field can increase the number of produced pairs.
