### Instructions for Data Collection

1. **Number of Paper Clips for 30-Turn Coil Without a Core:**
- Create a coil with 30 turns of insulated copper wire around the nail.
- Connect the wire to the D-cell batteries.
- After powering the coil, test how many paper clips it can pick up in three separate trials.
- Record the number of clips collected in each trial.

2. **Number of Paper Clips for 60-Turn Coil Without a Core:**
- Repeat the process with 60 turns of insulated copper wire.
- Again, perform three trials and record the results.

3. **Average Calculation:**
- Calculate the average number of paper clips picked up by adding the results from each trial and dividing by the number of trials for both the 30-turn and 60-turn coils.

4. **Ranking:**
- Rank the performance based on the average number of paper clips picked up in each coil.
