Faraday’s & Lenz Law | Electromagnetic Induction | IGCSE & O-Level | Part 5 | Physics with SMS

Описание: In this lecture, we explain Faraday’s Law of Electromagnetic Induction and Lenz’s Law, two core concepts of Electromagnetism in the IGCSE & O-Level Physics syllabus.

These laws help us understand how induced current is produced and why its direction opposes the change causing it—a key idea tested in Cambridge exams.

📘 Topics covered in this video:
✅ Magnetic flux and change in flux
✅ Faraday’s First Law – when an emf is induced
✅ Faraday’s Second Law – factors affecting induced emf
✅ Meaning and statement of Lenz’s Law
✅ Direction of induced current using Lenz’s Law
✅ Relation between Faraday’s Law and Lenz’s Law
✅ Simple examples:
• Moving magnet and coil
• Increasing/decreasing magnetic field
• Generator principle (basic idea)
✅ Common exam mistakes and marking points

🎯 This lesson is ideal for:
✔️ IGCSE Physics (0625) students
✔️ O-Level Physics (5054) students
✔️ GCSE Physics learners
✔️ Students revising electromagnetic induction
