The correct response is **battery**.
An electric current in an electromagnet is provided by a battery (or another power source) that supplies electricity to the wire coiled around the iron or steel core. The wire conducts the electric current, and when this current flows through the wire, it creates a magnetic field around the core, effectively turning it into an electromagnet.
