Motional EMF Electromagnetic Induction 2 in Hindi for Class 12

############################# Video Source: www.youtube.com/watch?v=71QyYgzruPI

In this Physics video in Hindi for Class 12 we explained self induction, self inductance and self-induced emf or back emf using faraday's law of electromagnetic induction and Lenz's law. This topic is from Chapter 6 : 'Electromagnetic Induction' for Class 12 from NCERT. • When electric current flows through a solenoid, a magnetic field is produced inside and hence, magnetic flux is created. When current varies, magnetic flux changes. According to faraday's law of electromagnetic induction, this change in flux produces induced emf. According to Lenz's law, this induced emf opposes its cause, which is the change in current. This opposing induced emf is called self-induced emf or back emf. • This phenomenon is known as self induction. • The property of the solenoid (also known as inductor) is known as self inductance. • 0:00 Introduction to Self induction and Back EMF • 1:47 Self Inductance • 8:41 Derivation of the expression for Self Inductance • 12:02 Derivation of the expression for Back EMF • 16:59 Current - Time graph for self induction • 21:46 Work done against Back EMF • 28:10 How is stored energy recovered from the inductor • 👇👇👇👇👇👇 𝑷𝑳𝑨𝒀𝑳𝑰𝑺𝑻 👇👇👇👇👇👇 • 🔴 Click here to watch the whole playlist on Chapter 6 : 'Electromagnetic Induction' for Class 12 : • • Physics 12th : Electromagnetic Induction • 👇👇👇👇👇👇 𝑷𝒓𝒆𝒗𝒊𝒐𝒖𝒔 𝑽𝒊𝒅𝒆𝒐𝒔 👇👇👇👇👇👇 • 🔴 Faraday's Law Lenz's Law • • Electromagnetic Induction - 1 || Fara... • 🔴 Motional EMF • • Motional EMF || Electromagnetic Induc... • 🔴 Eddy Current • • Eddy Current || Electromagnetic Induc...
