To create the strongest electromagnet, you would want to use materials that enhance the magnetic field produced by the electric current. The best combination would include:

  • An iron nail (which serves as the core to enhance the magnetic field)
  • Copper wire (which will carry the electrical current)
  • The 6-volt battery (which provides a higher voltage, leading to a stronger current)

Therefore, the correct choice is:

iron nail, copper wire, 6-volt battery.
