Quick explanation

Understand that moving a conductor through a magnetic field or having a changing magnetic field around a conductor can create an electromotive force (e.m.f.) in that conductor

  • This point belongs to Electromagnetic induction, especially Electromagnetic induction outcomes.
  • You need to be able to understand that moving a conductor through a magnetic field or having a changing magnetic field around a conductor can create an electromotive force (e.m.f.) in that conductor.
  • The key ideas to know are Know and Understand.
  • Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.

Description

Electromagnetic Induction

When a conductor moves through a magnetic field or when the magnetic field around a conductor changes, an electromotive force (e.m.f.) is induced in the conductor.

  1. a

    State the condition required for e.m.f. to be induced in a conductor.

    Aim for approximately 1 distinct marking point.
