Mini Magnetic Field Viewer Challenge
⚠️ Safety Warning
Iron filings can be messy. Avoid getting them near eyes or mouth. Wash hands after handling.
All experiments require adult supervision.
Materials You'll Need
Gather these 4 items before starting
💡 Tip: Check off items as you gather them to stay organized!
Step-by-Step Instructions
Follow these 7 steps carefully
place the white paper flat on a table.
Put the bar magnet in the center underneath the paper.
Slowly sprinkle iron filings over the top of the paper, covering the area around the magnet.
Gently tap the paper to help the filings align with the magnetic field lines.
Observe the pattern that forms — you will see curved lines running from one pole to the other.
Try rotating the magnet and see how the pattern changes.
Use tape to carefully preserve your pattern by pressing it onto the filings.
✅ Remember: Take your time with each step and ask an adult for help if needed!
The Science Behind It 🔬
Magnets create an invisible force field around them called a magnetic field. Iron filings are tiny pieces of iron that are attracted to the magnet. When you sprinkle them on paper, they line up along the magnetic field lines, making the invisible field visible! The lines go from the north pole to the south pole of the magnet. This is the same type of force that makes compasses point north — Earth itself is a giant magnet! This concept connects to many other areas of science, including astronomy, medicine, and environmental science.
