Below is a picture of an electromagnet made by wrapping a wire around an iron nail and connecting it to a battery. The electromagnet can be turned off by disconnecting it from the battery. A teacher helps students perform 2 experiments to test the variables that affect the electromagnet’s magnetic strength.
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.
Which question can be answered based on the results of Experiment 2?
(1 point)
Unfortunately, since the actual data from Experiment 2 is not provided in your message, I cannot reference specific results. However, I can tell from the description that Experiment 2 is designed to vary the battery voltage while keeping the number of coils constant.
Based on this design, the experiment can likely help answer questions related to how the voltage of the battery affects the strength of the electromagnet. A typical question that Experiment 2 could answer might be:
"How does changing the voltage of the battery affect the magnetic strength of an electromagnet, as measured by the number of paperclips it can pick up?"
To answer this question with the results of Experiment 2, one would compare the number of paperclips the electromagnet could pick up with batteries of different voltages, assuming that all other variables (such as the number of coils, the size of the nail, the type of wire, etc.) are kept constant.
