  Rotating magnetized white dwarfs are studied within the framework of general
relativity using Hartle's formalism. Matter inside magnetized white dwarfs is
described by an equation of state of particles under the action of a constant
magnetic field which introduces anisotropic pressures. Our study is done for
values of magnetic field below $10^{13}$ G -a threshold of the maximum magnetic
field obtained by the cylindrical metric solution- and typical densities of
WDs. The effects of the rotation and magnetic field combined are discussed, we
compute relevant magnitudes such as the moment of inertia, quadrupole moment
and eccentricity.
