  The ability for most hadrons to decay via strong interactions prevents the
direct measurement of their electromagnetic properties. However, a detailed
understanding of how these resonant states feature in scattering processes can
allow one to disentangle such information from photo production processes. In
particular, there has been increasing interest in the determination of magnetic
dipole moments using such methods. In a recent study, Gudino et al. provide the
first experimental determination of the magnetic dipole moment of the rho
meson. To facilitate a comparison with this experimental determination, we
present a calculation of the rho meson and pion electromagnetic form factors
calculated in the framework of Lattice QCD. Using the PACS-CS 2+1 flavour full
QCD gauge field configurations, we are able to access low $Q^2$ values at
near-physical quark masses. Through the use of variational techniques, we
control excited state systematics in the matrix elements of the lowest-lying
states and gain access to the matrix elements of the first excited state. Our
determination of the rho meson $g$-factor $g_{\rho} = 2.21(8)$ is in excellent
agreement with this experimental determination, but with a significantly
smaller uncertainty.
