Medicine & TechnologyKnowing the level of a planet’s magnetic field can be an important fact to know in the study of how they interact. But studying the fields of an exoplanet, outside of our solar system and orbiting a foreign star, can be a difficult task that researchers have not yet been able to achieve. Though in nearly two decades of looking past our solar system to investigate exoplanets, researchers have developed several methods to estimate magnetic fields at quite a distance.
