Chapter 17: Electromagnetic Induction
The laws of electromagnetic induction
(a) Define magnetic flux as the product of an area and the component of the magnetic flux density perpendicular to that area.
(b) Recall and solve problems using Φ = BA.
(c) Define magnetic flux linkage.
(d) Infer from appropriate experiments on electromagnetic induction:
i. that a changing magnetic flux can induce an e.m.f.
ii. that the direction of the induced e.m.f. opposes the change producing it
iii. the factors affecting the magnitude of the induced e.m.f.
(e) Recall and solve problems using Faraday’s law of electromagnetic induction and Lenz’s law.
(f) Explain simple applications of electromagnetic induction.
