  Using adaptive optics with the Multi-Unit Spectroscopic Explorer (MUSE) on
the Very Large Telescope (VLT), the Middle Ages Galaxy Properties with Integral
Field Spectroscopy (MAGPI) survey allows us to study the spatially resolved
Universe at a crucial time of ~4 Gyr ago ($z$ ~ 0.3) when simulations predict
the greatest diversity in evolutionary pathways for galaxies. We investigate
the radial trends in the star formation (SF) activity and luminosity-weighted
stellar ages as a function of offset from the star-forming main sequence (SFMS)
for a total of 294 galaxies. Using both H$\alpha$ emission and the 4000
Angstrom break (i.e., D4000) as star formation rate (SFR) tracers, we find
overall flat radial profiles for galaxies lying on and above the SFMS,
suggestive of physical processes that enhance/regulate SF throughout the entire
galaxy disc. However, for galaxies lying below the SFMS, we find positive
gradients in SF suggestive of inside-out quenching. Placing our results in
context with results from other redshift regimes suggests an evolution in
radial trends at $z$ ~ 0.3 for SF galaxies above the SFMS, from uniformly
enhanced SF at $z$ ~ 1 and $z$ ~ 0.3 to centrally enhanced SF at $z$ ~ 0 (when
averaged over a wide range of mass). We also capture higher local SFRs for
galaxies below the SFMS compared to that of $z$ ~ 0, which can be explained by
a larger population of quenched satellites in the local Universe and/or
different treatments of limitations set by the D4000-sSFR relation.
