This lesson covers the motor effect — the force on a current-carrying conductor in a magnetic field — as required by the Edexcel GCSE Physics specification (1PH0), Topic 8: Magnetism and Electromagnetism. You need to understand Fleming's left-hand rule, the equation F = BIl (Higher tier), and how a DC motor works.
When a current-carrying conductor (a wire with current flowing through it) is placed in a magnetic field, it experiences a force. This force can cause the conductor to move. This is called the motor effect.
For the motor effect to occur, you need:
