Magnetism: When Magnets Make Motors Move

How do electric motors make things spin? In this episode of GCSE Science Simplified, we explore the motor effect and how current-carrying wires in magnetic fields experience forces that produce motion. Learn how Fleming’s left-hand rule predicts the direction of force, how the force depends on current, wire length, and magnetic field strength, and how the commutator keeps a motor coil spinning continuously—illustrated with a fun roundabout analogy. Perfect for GCSE students who want to understand how invisible magnetic forces create real-life rotation in motors, fans, and toys.
