| Front | What is Lenz's law? |
| Back | The direction of induced current always acts in a way to oppose the change that causes it. I.e. when a north pole is pushed into a coil, it induces a current in the coil. This creates a north pole that pushes the magnet out. |
| Front | How you find the % uncertainty (using a graph) |
| Back | % uncertainty (using gradient) = ((best gradient - worst gradient)/ best gradient) x 100or% uncertainty = ((best y-intercept - worst y-intercept)/ y-intercept) x 100 |
