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

Answer 1

To make an effective electromagnet, the girl should use a metal rod for a core, copper wire, and a 12-volt battery. The metal rod acts as a core that enhances the magnetic field created by the flow of electricity through the copper wire.

So the correct response is:

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