Electromagnetic induction

20.5

What the syllabus asks of you

  • define magnetic flux as the product of the magnetic flux density and the cross-sectional area perpendicular to the direction of the magnetic flux density
  • recall and use Φ = BA
  • understand and use the concept of magnetic flux linkage
  • understand and explain experiments that demonstrate: • that a changing magnetic flux can induce an e.m.f. in a circuit • that the induced e.m.f. is in such a direction as to oppose the change producing it • the factors affecting the magnitude of the induced e.m.f.
  • recall and use Faraday’s and Lenz’s laws of electromagnetic induction
