Answer 1

To make a simple electromagnet, the girl would need a metal rod for a core, copper wire, and a 12-volt battery. Therefore, the correct choice is:

metal rod for a core, copper wire, 12-volt battery.

The metal rod, typically made of iron or steel, enhances the magnetic field created by the electric current passing through the copper wire.
