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

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

Answer 1

To make a simple electromagnet, the best option from the provided responses is:

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

Using a metal rod (typically iron) as a core enhances the magnetic field created by the current flowing through the copper wire.
