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

Answer 1

To make a simple electromagnet, the girl will need a metal rod for the core, copper wire, and a 12-volt battery. The metal rod serves as the core that enhances the magnetic field when the current flows through the copper wire.

So, the correct response is:

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