# Regents Physics - Electricity & Magnetism

Electricity and Magnetism play a profound role in almost all aspects of our daily lives... from the moment we wake up, to the moment we go to sleep (and even while we're sleeping), applications of electricity and magnetism provide us tools, light, warmth, transportation, communication, and even entertainment. Despite its widespread use, however, there is much we're still learning every day about these phenomena!
