  This paper investigates the effects of electromagnetic field on the
gravitational collapse in $f(\mathcal{R},\mathcal{T},\mathcal{Q})$ theory,
where $\mathcal{Q} = \mathcal{R}_{\varphi\vartheta}
\mathcal{T}^{\varphi\vartheta}$. For this, we assume dynamical cylindrically
symmetric self-gravitating geometry which is coupled with generalized
anisotropic matter distribution as well as dissipation flux. We adopt the model
$\mathcal{R}+\Phi\sqrt{\mathcal{T}}+\Psi\mathcal{Q}$ to formulate the
corresponding dynamical and transport equations by employing the Misner-Sharp
as well as M\"{u}ler-Israel Stewart formalisms, where $\Phi$ and $\Psi$ are
real-valued coupling constants. The influence of state variables, heat
dissipation, charge and the bulk viscosity on the collapsing phenomenon is then
studied by establishing some relations between these evolution equations.
Moreover, the Weyl scalar and the modified field equations are expressed in
terms of each other. We apply some constraints on the considered modified model
and the fluid configuration to obtain conformally flat spacetime. Finally, we
address different cases to check how the modified corrections and charge affect
the collapse rate of cylindrical matter source.
