This DigiKit was developed for introductory physics and astronomy courses to help students forge deeper understandings of how electrical currents behave and influence magnetic fields in both large and smaller-scale systems. Students will explore how a current-carrying wire suspended above a table can be a model for the much larger electrojet current system that circles the atmosphere roughly 200 km above Earth's surface. Electrojets push a huge amount of electrical charge around the poles every second and are responsible for dazzling auroras and for potentially damaging geostorms. The linchpin of this resource collection is the turn-key lecture tutorial, containing a lab activity and datasets for student analysis and integration of mathematics. The DigiKit offers simulations of the auroral electrojet phenomenon, conceptual background information, and six different sources of free-access observational tools your students can use to extend the learning.
