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

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. For more details please watch the video and share it with your friends and classmates. If you have questions drop them in the comments INSHAALLAH I will answer them. Keep supporting and please subscribe to my channel for more related videos. Remember me in your Prayers. JAZAK ALLAH What factors limit the size of Back Emf? Why does back Emf tends to decrease as rate of doing work increases? In Faraday’s experiment, what should be the advantage of using coils with many turns? Show that the relationship ∈ = "∆∅" /"∆t" is dimensionally consistent. Give the formulae for the flux linkage in terms if angular orientation. How electromagnetic brake works explain? How Eddy’s current is minimized in transformer? How electromagnetic induction is used in cooks tops in electric ranges? What is meant by term back emf in any electric motor operation. Why it is an advantage for the armature to rotate in a radial magnetic field rather than a uniform one? Which material would you prefer while making transformer core; iron, solid soft iron, laminated soft iron, aluminum? (b) What is the reason for using this material?
