After pressing the button (without releasing it) one LED lights up briefly. Releasing the button prompts the other LED to lights up briefly. This experiment demonstrates that the coil opposes any change in current first by blocking the current and forcing the current to pass through the first LED and then, when the button is released, by releasing it's stored energy over the second LED.
|All components on the breadboard. Two 470 ohm resistors in parallel were used to counter for the 1/8 watt resistors that I use.|
