| Question | Answer |
| Electromagnetic Induction | When an emf is induced by a change in the magnetic flux linking a circuit |
| Faraday's law | The magnitude of the induced emf is proportional to the rate of change of magnetic flux |
| Formula for faraday's law | E = dΦ/dt |
| Lenz's law | The direction of the induced emf always opposes the charge causing it |
| Formula combing Faraday's law & Lenz's law | E = - dΦ/dt |
| Function of generators | Convert mechanical energy into electrical energy |
| Process undergone in generators | Rotation of coil of wire in a magnetic field --> change in flux linking the coil --> induction of an emf |
