A student conducted an experiment where they made an electromagnet. They used a battery that was 10V, but changed the varying number of turns around the nail. Then the student tested how many pins it attracted. They recorded their data in the table below.

Question

Based on the investigation the student completed, what would be the best conclusion for this student's work?
Type Answer HERE:
The number of turns on an electromagnet does not determine the strength of the magnetic field it creates. Therefore more turns on an electromagnet will pick up an increasing number of pins.
The number of turns on an electromagnet does not determine the strength of the magnetic field it creates. Therefore more turns on an electromagnet will pick up less pins.
The number of turns on an electromagnet does impact the strength of the magnetic field it creates. Therefore more turns on an electromagnet will pick up an increasing number of pins.
The number of turns on an electromagnet does impact the strength of the magnetic field it creates. Therefore less turns on an electromagnet will pick up an increasing number of pins.

Answer 1

The best conclusion for this student's work is:

The number of turns on an electromagnet does impact the strength of the magnetic field it creates. Therefore more turns on an electromagnet will pick up an increasing number of pins.

This conclusion aligns with the principle that increasing the number of turns of wire around the core generally increases the strength of the electromagnet, which in turn allows it to attract more pins.
