To build an electromagnet, start by wrapping a coil of insulated wire around a piece of ferromagnetic material, such as an iron nail. Connect the ends of the wire to a power source, such as a battery, and the electromagnet will be activated when the current flows through the wire. Make sure to wind the wire tightly and evenly around the ferromagnetic material to create a strong magnetic field.
