The three items used to make an electromagnet are:

a. A battery d. A nail e. Some thin wire

Here's a step-by-step guide on how to make an electromagnet:

1. Take the thin wire and wrap it around the nail. The more turns of the wire, the stronger the electromagnet will be.
2. Strip the ends of the wire to expose the metal.
3. Connect one end of the wire to the positive terminal of the battery and the other end to the negative terminal.
4. Your electromagnet is now ready. You can test it by bringing it close to some small metal objects. The electromagnet should attract them.
