Face-on rendering of the magnetic field strength of galactic disk after t = 2.0 Gyr. Simulations with feedback, comparing the effect of different Jeans floor on the evolution. Top panel show the Low resolution simulation and bottom the medium resolution. We can see that we get no significant amplification in the low resolution, while strong amplification is seen in the medium resolution. Too high Jeans floor diminishes the dynamo processes as the smallest collapse length becomes too large.
