Quick explanation

Identify and apply the relative directions of force, magnetic field, and induced current

  • This point belongs to Electromagnetic induction, especially Electromagnetic induction outcomes.
  • You need to be able to identify and apply the relative directions of force, magnetic field, and induced current.
  • The key ideas to know are State and Use.
  • Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.

Description

Induced Current in a Circuit

A coil of wire is placed in a changing magnetic field. As the magnetic field strength increases, an induced current flows in the coil.

  1. a

    State the direction of the induced current when the magnetic field strength is increasing.

    Aim for approximately 1 distinct marking point.
