Revision notes for Edexcel IAL Physics Unit 4
| Front | What is Faraday's law of induction? |
| Back | The induced e.m.f. in a circuit is equal to the change of magnetic flux linkage through the circuit over time.\(\varepsilon=\frac{-\Delta(N\Phi)}{\Delta t}\) |
| Front | What is Lenz's law? |
| Back | The direction of the induced current is always such as to oppose the change that causes the current. |
| Front | What is a force field? |
| Back | A region in space where a particle experiences a force. |
