Please answer asap <3 The data from the electromagnet experiment suggest some relationships between a cause (the construction of the electromagnet) and an effect (the number of paperclips lifted).

Think about the differences between Magnets A, B, and C. Now, select a question that you could ask to help you understand how the construction of an electromagnet affects its strength.

1) What effect does increasing the number of wraps of wire have on the strength of the electromagnet?

2) Will the magnet pick up other objects?

3) Does the battery need to have energy left in it?

4) Why does the nail pick up paper clips?
