Electric motors - Full Lesson

Lesson designed to build upon prior knowledge of magnetic fields and electric current. Covers the motor effect and how to increase the strength of an electric motor - includes practice questions for students.

Ideal for AQA GCSE (9-1) P7, Cambridge iGCSE P9 and more

Developing: State that a current-carrying coil in a magnetic field experiences a turning effect and that the effect is increased by: – increasing the number of turns on the coil – increasing the current – increasing the strength of the magnetic field.

Secure: Relate this turning effect to the action of an electric motor including the action of a split-ring commutator.

Exceeding: Apply Fleming’s left-hand rule to determine the direction of rotation of a current carrying coil in a a magnetic field.
