Introduction: Today’s laboratory experiment consisted in introducing the concept of  magnetism starting by studying a permanent magnet. To understand the concept of  magnetic fields, we measured the magnetic force of a permanent magnet around it. We  study how the magnetic force changed with distance, understanding where its maximum  and minimum value was located. We also learned how to physically draw the magnetic  field of a permanent magnet using only a compass, pencil, and piece of paper. Analysis is in following pages.

Conclusion: In this experiment I learned about how magnetic fields for permanent magnets

Unformatted text preview: behave. I was able to prove that the field is inversely proportional to the square distance by graphing a magnetic force vs. distance graph and analyzing that the best fit was an inverse square fit. The reason a compass is useful to draw a magnetic field is because magnets tend to line themselves with magnetic field lines. This exercise helped me understand better the shape, strength, and direction of a magnetic field; as well as learning that the Earth is a huge magnet itself. Drawing the magnetic field also proved the fact that opposite poles attract each other, while like poles repel each other....
