Secondary 2 students recently conducted an engaging physics investigation to explore the concept of magnetic fields. During the activity, students used a bar magnet, iron filings, and a sheet of paper to visualize the invisible magnetic field surrounding the magnet.
In the experiment, students carefully placed the paper over the bar magnet and gently sprinkled iron filings on top. As they lightly tapped the paper, the iron filings arranged themselves into curved patterns. These patterns clearly showed the shape and direction of the magnetic field lines, helping students identify where the magnetic field is strongest, particularly near the poles of the magnet.
Through observation and discussion, students discovered that magnetic fields form distinct patterns around magnets and that the strength of the field varies depending on the distance from the magnet. The hands-on investigation allowed students to directly observe a phenomenon that is usually invisible.
After completing the experiment, students documented their observations, procedures, and conclusions in a structured Science Report. This report helped them develop their scientific writing skills while reflecting on their experimental findings.
The activity encouraged curiosity, critical thinking, and collaboration as students worked together to uncover how magnetic fields behave in the physical world
