Trial 3: 9 coils

(3 points)

Trial Number of paper clips attracted Number of batteries Battery level Number of coils Material type Size of rod
1 ____ 3 full 3 iron L
3 _____ 3 full 5 iron L
2 _____ 3 full 9 iron L

Answer 1

Based on the information provided regarding the trials and their variable of the number of coils used, it appears that you are assessing how the number of coils affects the performance of the electromagnet in attracting paper clips.

Here is how you can fill in the missing data for each trial based on the experiments:

Trial 1:

• Number of paper clips attracted: This needs to be provided or inferred from the data you already have. If Trial 2 and Trial 3 are validating that as the number of coils increases the number of paper clips attracted increases, then you could suggest a low number here.

Trial 2:

• Number of paper clips attracted: This should be the highest of the three trials if the trend of increased coils results in increased attraction holds true.

Trial 3:

• Number of paper clips attracted: This would typically be the lowest number because it has the least number of coils compared to the other trials.

Please provide the specific numbers for "Number of paper clips attracted" in Trials 1, 2, and 3 to complete the table. You should relate the number of coils to the performance you've observed (e.g., more coils = more paper clips attracted). If further information is available or you have made observations, please share, so I can assist further!
