Experiment 1
The students build an electromagnet using a 4.5 volt battery connected to an iron nail with coils wrapped around it. They change the number of coils around the nail and record how many paperclips the electromagnet can pick up each time. The results are shown in the table below.
Experiment 2
In the second experiment, the students keep the same number of coils around the nail and records how many paperclips the electromagnet can pick up using different batteries.

Based on the results of Experiment 2, the question that can be answered is:
How is the strength of an electromagnet affected by the voltage of the battery?
In this experiment, the students tested the electromagnet's strength (indicated by how many paperclips it could pick up) while varying the voltage produced by different batteries, keeping the number of coils constant. This allows them to draw conclusions about the relationship between the voltage and the strength of the electromagnet.
