1. A piece of iron or another ferromagnetic material: This forms the core of the electromagnet.

2. Insulated wire: This is wrapped around the core. When an electric current is passed through the wire, it creates a magnetic field.

3. A power source: This is needed to generate the electric current. The power source can be a battery or any other source of electricity.
