The best description of how to build an electromagnet is:

**Attach a wire to one end of a battery, wrap the wire around an iron or steel core, and attach the other end of the wire to the other end of the battery.**

This description captures the essential steps of creating a closed circuit that allows current to flow through the wire, which generates a magnetic field around the iron or steel core, making it an electromagnet.
