An analysis is given of the kinetic equilibrium of beta-processes in high-temperature, superdense, strongly magnetized matter. The ratio of the neutron and proton number densities in a quantizing magnetic field is evaluated. Numerical calculations show that if the electrons (or positrons) have a large chemical potential, the value of this ratio in an ultrastrong magnetic field will be much lower than the corresponding ratio when H = 0, while if there are small departures from equilibrium the relaxation time of the beta-processes will be about half as long as in the field-free case. The processes discussed may be useful for describing the evolution of massive, highly magnetized stars at the stage just prior to a supernova explosion.
