Electromagnetic induction

The video explains electromagnetic induction, which occurs when a conductor is placed in a changing magnetic field. This principle is used in power stations to generate electricity by spinning a coil inside a magnetic field, inducing a current. Additionally, electromagnetic induction enables wireless charging of devices like mobile phones, where an alternating current in a transmitter coil creates a magnetic field that induces a current in the phone's receiver coil, charging the battery.
