Why outlets spark when unplugging - EMF & Inductors

Dianna from Physics Girl introduces a video on induction, focusing on a demonstration involving electromagnets and sparks. She explains the concept of induction, its counterintuitive nature, and its relation to magnetic fields and currents. The video covers the role of inductors, energy conservation, and Faraday's Law, using metaphors like a water hammer to aid understanding. Dianna also highlights the practical applications of induction, such as in car ignitions and coin shrinking. The video concludes with thanks to MIT for their support.
