glass rod for a core, copper wire, 12-volt battery
glass rod for a core, copper wire, 12-volt battery

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

Answer 1

To make a simple electromagnet, the girl would need a core material that can conduct magnetism effectively. Among the options provided, the best choice is:

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

This combination will allow her to create a functional electromagnet, as the metal rod will enhance the magnetic field produced by the electric current flowing through the copper wire.
