What the motor effect is

What the motor effect is

The motor effect is the force on a current-carrying conductor placed in a magnetic field. In GCSE physics we use conventional current, which goes from the positive terminal to the negative terminal.

  3. /12.3 The motor effect

Step-by-step lessons on Edexcel GCSE Physics 12.3 The motor effect, covering 12.3.1 The motor effect, 12.3.2 Fleming's left-hand rule, 12.3.3 Force on a conductor, and 12.3.4 Electric motors. Each one builds up to exam-style questions. Master the required practical work and core equations early, since both papers can draw on content and maths skills from across the whole specification.
