  Individual low-energy E1 toroidal and compressional states (TS and CS)
produced by the convective nuclear current ${\bf j}_{\rm c}$ were recently
predicted for $^{24}$Mg in the framework of quasiparticle
random-phase-approximation (QRPA) with Skyrme forces. In the present QRPA study
with Skyrme parametrization SLy6, we explore in more detail properties of these
states (toroidal and compressional responses, current distributions, and
transitions probabilities $B(E1K, 0^+0 \to 1^-K),\; B(E3K, 0^+0 \to 3^-K)$,
$B(M2K, 0^+0 \to 2^-K)$ with $K=$0 and 1) and analyze the possibility to
discriminate and identify TS in inelastic electron scattering to back angles.
The interplay of the convective ${\bf j}_{\rm c}$ and magnetization ${\bf
j}_{\rm m}$ nuclear currents is thoroughly scrutinized. A two-step scheme for
identification of TS in $(e,e')$ reaction is proposed. The key element of the
scheme is the strong interference of the orbital and spin contributions,
resulting in specific features of E1 and M2 transversal form factors.
