|Comments               = The estimated merger rate of binary BH systems is ~20 times smaller than that estimated for FRBs, and thus the theory can only account for the full population in the unlikely case that only <5% of FRBs are cosmological.

== Model Description ==

A binary BH system in which at least one of the spinning BHs carries a charge would induce a global magnetic dipole normal to the orbital plane. During inspiral, as the orbital separation decreases, the magnetic flux of the system changes rapidly, which leads to particle bunching and the emission of coherent curvature radiation. And for some minimal values of the charge of the BH,  this scenario could produce an FRB and a sGRB \cite{Zhang:2016rli}. The detection of both signals could provide a lower limit on the charge, and the non-detection of a sGRB could provide an upper limit.
