Electromagnets and the Motor Effect — Interactive Lesson (Ages 14–16)

Every ceiling fan and blender has an electric motor inside. Discover how electricity and magnetism make things spin. This 21-slide interactive lesson on motor effect takes pupils from first ideas to exam-style explanations, with 13 self-marking activities and nothing to prepare beforehand.

Teaching Electromagnets and the Motor Effect in GCSE Physics

Pupils describe magnetic fields around permanent and induced magnets, the field around a current-carrying wire and a solenoid, and how to make an electromagnet stronger. They use Fleming's left-hand rule and F = B × I × l, explain how a split-ring commutator keeps a d.c. motor turning, and apply the motor effect to loudspeakers.

What Pupils Will Learn

• Describe magnetic fields around permanent magnets.
• Describe the magnetic field around a current-carrying wire and a solenoid.
• Explain how to make an electromagnet stronger.
• Use Fleming's left-hand rule and F = B × I × l.
• Explain how a simple electric motor works.
