In the paper, we devote to broadening the current global regularity results for the two‐dimensional magnetic Bénard fluid equations. We study three cases: (i) fractional Laplacian dissipation (‐ Δ)αu, partial magnetic diffusion ( x 2 x 2 2 b 1 , x 1 x 1 2 b 2 ) , and Laplacian thermal diffusivity Δθ; (ii) partial fractional dissipation ( Λ x 2 2 α u 1 , Λ x 1 2 α u 2 ) , partial magnetic diffusion ( x 2 x 2 2 b 1 , x 1 x 1 2 b 2 ) , and Laplacian thermal diffusivity Δθ; (iii) partial fractional magnetic diffusion ( Λ x 2 2 β b 1 , Λ x 1 2 β b 2 ) , Laplacian thermal diffusivity Δθ, and without Laplacian dissipation Δu (i.e., μ = 0 ), and establish the global regularity for each cases.
