Electromagnetism is one of the cornerstones of modern science and technology, linking the invisible world of electric current to the tangible effects of magnetic force. Hans Christian Ørsted’s 1820 discovery—that a compass needle deflects when placed near a current-carrying conductor—ignited the study of electromagnetism and, ultimately, ushered in the electric age. The Oersted’s Law Apparatus distills that pivotal moment into a durable, portable teaching instrument that lets learners witness the current-magnetic-field relationship first-hand.
