  Diffusive limit of the non-cutoff Vlasov-Maxwell-Boltzmann system in
perturbation framework still remains open. By employing a new weight function
and making full use of the anisotropic dissipation property of the non-cutoff
linearized Boltzmann operator, we solve this problem with some novel treatments
for non-cutoff potentials $\gamma > \max\{-3, -\frac{3}{2}-2s\}$, including
both strong angular singularity $\frac{1}{2} \leq s <1$ and weak angular
singularity $0 < s < \frac{1}{2}$. Uniform estimate with respect to the Knudsen
number $\varepsilon\in (0,1]$ is established globally in time, which eventually
leads to the global existence of solutions to the non-cutoff
Vlasov-Maxwell-Boltzmann system as well as hydrodynamic limit to the two-fluid
incompressible Navier-Stokes-Fourier-Maxwell system with Ohm's law. The
indicators $\gamma > \max\{-3, -\frac{3}{2}-2s\}$ and $0 < s <1$ in this paper
cover all ranges that can be achieved by the previously established global
solutions to the non-cutoff Vlasov-Maxwell-Boltzmann system in perturbation
framework.
