The combined quasineutral and inviscid limit for the Vlasov-Maxwell- Fokker-Planck system is rigorously derived in this paper. It is shown that the renormalized solution of Vlasov-Maxwell-Fokker-Planck system converges to the strong solution of the so-called electron magnetohydrodynamics equations. The proof of convergence result relies on the weak convergence compactness method and the relative-entropy method.
