Induction - An Introduction: Crash Course Physics

The video explores the concept of magnetic induction, starting with the discovery that electric currents can create magnetic fields and the subsequent question of whether magnetic fields can induce electric currents. Faraday's experiments led to the understanding that a changing magnetic field induces an electromotive force (EMF) in a loop of wire. The video explains magnetic flux and factors affecting it, such as field strength, loop area, and angle. It covers calculating induced EMF and using Lenz's Law to determine current direction. Practical applications, including hard drives, are discussed.
