The generated output is alternating electrical power in the form of current and alternating voltage. The working principle of the AC generator is based on Faraday’s Law of electromagnetic induction.
WebSo, go ahead and check the Important Notes for Class 12 Physics Electromagnetic Induction. Whenever the magnetic flux linked with an electric circuit changes, an emf is induced in the circuit. This phenomenon is called electromagnetic induction. Faraday’s Laws of Electromagnetic Induction Web8 apr. 2024 · Complete answer: Induced current: It is the current that is induced in a conducting loop which is exposed to a changing magnetic field is known as induced …
WebThus, the rate of change of flux ΦB will induce an emf, which is given by: ϵ = − d ϕ B d t = − d d t ( B l x) = − B l d x d t = B l v. Where, the speed of conductor (PQ), v = -dx/dt and is the formula of induced emf. This induced emf due to the motion of an electric conductor in the presence of the magnetic field is called motional emf.
