abstract = "We study the role of time dependent magnetic ellipticities on the
calculation of the braking index of pulsars. Moreover, we study
the consequences of such a magnetic ellipticity on the amplitude
of gravitational waves (GWs) generated by pulsars with measured
braking indices. We show that, since the ellipticity generated by
the magnetic dipole is extremely small, the corresponding
amplitude of GWs is much smaller than the amplitude obtained via
the spindown limit. Since only nine of more than 2000 known
pulsars have accurately measured braking indices, we extended this
study to all known pulsars, in particular to what concerns the GW
generation. Our results show that the GW amplitude is at best h ~
10^{-28}. This leads to a pessimistic prospect for the detection
of GWs generated by these pulsars, even for Advanced LIGO and
Advanced Virgo, and the planned Einstein Telescope, if the
ellipticity has magnetic origin.",
