The variation of pressure-gradient-driven turbulence with plasma$$\beta$$(up to$$\beta \approx 15\,\%$$) is investigated in linear, magnetized plasma. The magnitude of magnetic fluctuations is observed to increase substantially with increasing$$\beta$$. More importantly, parallel magnetic fluctuations are observed to dominate at higher$$\beta$$values, with$$\delta B_\parallel / \delta B_\perp \approx 2$$and$$\delta B / B_0 \approx 1\,\%$$. Parallel magnetic fluctuations are strongly correlated with density fluctuations and the two are observed to be out of phase. The relative magnitude of and cross-phase between density and parallel magnetic field fluctuations are consistent with the dynamic pressure balance ($$P+{B_{0}^2}/{2\mu _0} = \textrm {constant}$$). A local slab model theory for electromagnetic, modified drift Alfvén waves, including parallel magnetic fluctuations, shows partial agreement with experimental observations.
