Massive scalar field quasinormal modes of a Generic-class of magnetically charged regular black hole
Using the third-order WKB approximation method,the quasinormal modes of magnetically charged regular black holes in nonlinear electrodynamics were investigated.The study focused on the quasinormal modes of Bardeen-class,Hayward-class,and New-class black holes with magnetic charge under the perturbation of a massive scalar field,and analyzed the impact of the scalar field mass on the quasinormal mode frequencies.The numerical results indicate that as the increasing of the perturbing scalar field mass,the oscillation frequency of the black hole spacetime accelerates,while the damping rate of oscillations slows down,which means that the quasinormal modes decay more slowly for particles in a large mass field.Additionally,it was found that there is an almost linear relationship between the real and imaginary parts of the quasinormal mode frequencies as the scalar field mass varies.
