  Vector mesons and the $W$ gauge boson share some common features, such as the
spin and a very short lifetime. The electromagnetic properties of the $W$ are
linked to its gauge nature and thus a big effort has been devoted to measure
them, while accounting for its instability. In this work, we elaborate on how
these ideas can be translated to study vector mesons. We focus in the unstable
property of such states and the restrictions from electromagnetic gauge
invariance, describing the differences and similarities. Then, we describe the
four pseudoscalars electroproduction as an analog to the $e^+e^- \to 4
fermions$ process, used to study the electromagnetic properties of the $W$
boson. We point out that the current experimental capabilities are reaching the
possibility to measure the magnetic dipole moment of light vector mesons.
