Some radiopulsars have anomalous braking index values ?. It is shown that such anomalous values may be related to nondipolar magnetic field. Precession of a neutron star leads to rotation (in the reference frame of the star) of its angular velocity Ω around the direction of neutron star magnetic dipole m with an angular velocity Ωp. This process may cause altering of electric current flowing through the inner gap and consequently the current losses on the time-scale of precession period Tp= 2π/Ωp. It occurs because the electric current in the inner gap is determined by Goldreich-Julian charge density ρGJ=-Ω·B/(2πc), that depends on the angle between direction of small scale magnetic field and the angular velocity Ω.
