Time plots for the medium resolution feedback runs with varying Jeans floor. The left and right panel shows the evolution of B_rms and α_MW respectively. Darker colors represents higher Jeans floor. We can see that there is a positive dependence on the Jeans floor for the amplification rate, as long as a “critical” collapse length is resolved. The normalized Maxwell stress lie around α_MW = 0.1 − 0.3 for all runs. There is additional stress within the N_J = 30 simulation during the early amplification phase with around α_MW = 0.4.
