<p>Understanding how the magnetic activity of low-mass stars depends on their fundamental parameters is an important goal of stellar astrophysics. Previous studies suggest that the stellar mass and rotation period both play important roles in determining the overall activity level of a star. However, we currently have little information on the role of metallicity. In this poster, we study how magnetic activity scales with stellar metallicity. Specifically, we use photometric variability as a proxy for magnetic activity. Using a sample of over 3000 low-mass stars, we demonstrate that, at fixed stellar mass and rotation, more metal-rich stars are generally more magnetically active.</p>
