Final answer:
To build a temporary magnet, an electromagnet can be created using a battery, a wire coiled around an iron nail, and several paper clips to demonstrate magnetism. The correct items necessary for this demonstration are option C: a battery, an iron nail, a wire, and several paper clips.
Step-by-step explanation:
To build and demonstrate a working temporary magnet, we can use the items from the table that are needed to create an electromagnet. From the given options, the correct items that can be used together are a battery, an iron nail, a wire, and several paper clips. Here's why this combination is correct:
- The battery provides a source of electric current.
- The wire is coiled around the iron nail to create a solenoid.
- The iron nail acts as a core that becomes magnetized when the electric current flows through the wire.
- Paper clips are made of metal and will be attracted to the magnetized iron nail, demonstrating the temporary magnetism.
Therefore, option C is the accurate answer: "A battery, an iron nail, a wire, and several paper clips will accomplish this task." These items work together to build a temporary magnet, also known as an electromagnet, which exists only while the electric current is flowing. The permanent magnet and ammeter mentioned in the other options are unnecessary for creating a temporary magnet in this context.
