The effect of magnetic fields complicates the analysis of nonradial pulsations of stars. The angular dependence of the eigenfunction of a pulsation mode cannot be represented by a single spherical harmonic, and another type of oscillations enters into the equations. We discuss different methods employed to analyse nonradial pulsations in the presence of a magnetic field and compare the results from the different methods. Then, we discuss some important properties caused by the presence of a strong magnetic field, and discuss some asteroseismological works.
