Conceptual Questions I CH # 14 Electromagnetic Induction I 2nd Year Federal,KPK Board 2021 Edition

Описание: Assalamualikum Dear students in this video we are going to discuss Conceptual Questions of CH # 14 Electromagnetic Induction.
Whenever the magnetic flux through the conductor is changing an emf is induced in the coil this phenomenon is called Electromagnetic Induction.
