To the left we have set up another experiment, that looks almost like the one on the previous page. In the upper part we have a battery, a switch, and an electromagnet.
Below the electromagnet we have set up another iron core with an insulated copper coil around it. We have then connected a light bulb to the lower coil.
Now, once again, flick the switch, and watch what happens.
