GCSE AQA Physics Flashcards (Combined only!)
| Front | Explain how an electric motor works |
| Back | A current flows through the coil. This induces a magnetic field around the coil. The magnetic field around the coil interacts with the magnetic field around the magnet . Therefore, a force is exerted on the coil due to the motor effect. The forces on each side of the coil act in opposite directions which makes the coil rotate |
| Front | The direction of a magnetic field can be found using what instrument |
| Back | a compass |
| Front | A permanent magnet produces |
| Back | its own magnetic field |
