A Level Physics Magnetic Fields | Lesson 5 | KYM with Usman Aslam

How do we measure magnetic fields, calculate magnetic flux, and understand how changing magnetic fields induce an e.m.f.? In Lesson 5 of our A2 Level Physics Magnetic Fields series, we explore the Hall probe and the fundamental laws of electromagnetic induction, with a focus on understanding the concepts and applying them to exam-style questions. In this lesson, we cover: The Hall probe and how it is used to measure magnetic flux density Magnetic flux and the factors affecting it Faraday’s law of electromagnetic induction Lenz’s law and the direction of induced e.m.f. and current The relationship between changing magnetic flux and induced e.m.f. Key equations, conceptual applications, and exam-relevant tips for Cambridge A Level Physics Whether you're strengthening your understanding of electromagnetic induction or revising for your A2 Physics exams, this lesson will help you build confidence with the concepts, equations, and applications of magnetic fields.
