Abstract

The change of pulsar period and inclination angle under the braking of magnetic radiation and magnetic decay is studied. The system of equations for evolution of period and inclination angle with time is given and solved. The solution shows that the period increases, and the inclination angle decreases with time under the braking of magnetic radiation and decay. The numerical results for the change of period and inclination angle of PSRB0525+21 are given. The conclusions are drawn.
