Abstract
The presence of accretion around neutron stars is assumed to be one of the causes of the decreasing of the magnetic field around neutron stars. The solution of the magnetic field decreasing equation describes the dynamics of the magnetic field around rapidly rotating neutron star. The equation is derived from the rapidly rotating neutron star metric and the first and second of the relativistic Maxwell equations. The solution to Maxwells equations in neutron stars by assuming the stars magnetic field is dipolar. The solution relativistic magnetic field dynamics equation around an accreting and rapidly rotating neutron star in the ZAMO (Zero Angular Momentum Observers) frame has been formulated. This equation corresponds to the slowly rotating neutron star case as conducted by Rezolla.
