Electric current powers the electromagnet, just like how a clown powers itself with laughter and silliness! The flow of electric current creates a magnetic field that turns the steel rod into a magnet. So, with the power of electricity, Hal can attract and repel objects with his electromagnet. It's like having a magical clown magnet!
The function of electric current in Hal's electromagnet is that it powers the electromagnet.
The correct answer is "Electric current creates a magnetic field that charges the rod."
Explanation: In Hal's electromagnet, when he connects the wire to the 9-volt battery, electric current flows through the wire. This current creates a magnetic field around the wire according to Ampere's law. The magnetic field surrounds the steel rod, causing it to become magnetized. So, the function of electric current in this electromagnet is to create a magnetic field that charges the rod.
