             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.",
