### Data Analysis and Average Calculation
#### Number of Loops Test
| Tested Component | Trials | Number of paper clips (Trial 1) | Number of paper clips (Trial 2) | Number of paper clips (Trial 3) | Average for Trials | Ranking |
|------------------|--------|----------------------------------|----------------------------------|----------------------------------|---------------------|----------------------------|
| 30-turn coil | | 3 | 4 | 3 | (3 + 4 + 3) / 3 = 3.33 | 2 (Rank 2) |
| 60-turn coil | | 7 | 8 | 7 | (7 + 8 + 7) / 3 = 7.33 | 1 (Rank 1) |

### Control Configuration
The coil configuration that served as the control during these experiments was the 30-turn coil without a core. This was important because it provided a baseline measurement for comparison against the other variables tested (increasing the number of turns, changing the diameter, adding an iron core, and doubling the current). The control allows for a clearer understanding of how each modification impacts the performance of the electromagnet, isolating the effect of each variable being tested.
