Electromagnetic induction and alternating current are fundamental concepts in physics and electrical engineering, closely related to each other.
Electromagnetic induction is the process of generating an electromotive force (emf) or voltage across a conductor when it is exposed to a changing magnetic field. This phenomenon was discovered by Michael Faraday and is described by Faraday's law of electromagnetic induction.
Alternating current is an electric current that periodically reverses direction. In an AC circuit, the flow of electric charge continuously changes direction, typically following a sinusoidal waveform.
Abhi se kuch ghanto baad mera physics ka exam h bht mst lacture tha it's helpful mam 🙃
