Based on the options provided, the phenomenon most likely being tested during Investigation #1 is:

**(D) Wire wrapped around an iron nail attached to the poles of a battery will produce a magnetic force.**

This option suggests an investigation into how an electromagnet is created, which is typically tested using a wire (which conducts electricity) wrapped around a ferromagnetic material (like an iron nail) connected to a power source (such as a battery). When the circuit is completed, the electric current flowing through the wire generates a magnetic field, thereby demonstrating the principles of electromagnetism.

I apologize for the confusion. Let's analyze the choices again to determine the most appropriate phenomenon that might be tested during Investigation #1:

- **(A)** An iron nail is a natural magnet.
This statement is generally not true; an iron nail itself is not a natural magnet without magnetization.

- **(B)** An iron nail has to be used to create an electromagnet.
This suggests that the nail is necessary but doesn't directly address the effect under investigation.

- **(C)** A small battery has stored magnetism that can be used to attract paper clips.
This statement is inaccurate because while a battery can create a magnetic field when used in a circuit, it doesn't "store magnetism" in the way this statement suggests.

- **(D)** Wire wrapped around an iron nail attached to the poles of a battery will produce a magnetic force.
This describes the principle of creating an electromagnet when an electric current flows through the wire, demonstrating that the configuration produces magnetic force through electricity.

Given this analysis, **(D)** is the most accurate response regarding the testing of a phenomenon involving electromagnetism. If you're looking for a different interpretation or context, please provide more information, and I can reassess!
