Magnetars are our best natural laboratories for physics in the ultra-magnetized regime. In this seminar, we look into the dynamic phenomena exhibited by magnetars, from their rapid and intense bursts to their potential role as multimessenger sources. Alongside this explosive variability, we will examine their persistent emission. We will discuss how X-ray polarimetry now offers a direct observational handle on QED effects such as vacuum birefringence, turning a decades-old theoretical prediction into a measurable signature. We will explore the latest observational and theoretical advancements, and we will touch upon future prospects to enhance our observational capabilities.
