Lenz’s Law = Conservation of Energy? | Class 12 | Chapter 6 | EMI
In this video, we explain Lenz’s Law of Electromagnetic Induction, an important concept from Class 12 Physics (NCERT Chapter 6).
You will learn:
✔ What is Lenz’s Law?
✔ Why induced current always opposes the change in magnetic flux
✔ Relation between Faraday’s Law and Lenz’s Law
✔ Real-life examples (magnetic braking, induction stove, damping coil)
✔ Concept questions for board exams, NEET & JEE
🧲 Definition:
Lenz’s Law states that:
👉 The direction of induced current is such that it opposes the change in magnetic flux that produced it.
📌 Significance:
Ensures conservation of energy
Explains direction of induced EMF
🔔 Watch till the end for exam questions + quick memory trick!
