Visualize magnetic fields by creating maps with iron filings and magnets. Learn how magnetic fields move and interact with objects around them.
If a magnet is placed under a sheet of paper, then iron filings will align along the magnetic field lines, revealing the field's pattern.

Step 1: Place the bar magnet on a flat surface.
Step 2: Lay a sheet of white paper over the magnet.
Step 3: Gently sprinkle iron filings over the paper.
Step 4: Tap the paper lightly to help the filings align along the magnetic field lines.
Step 5: Use a ruler to measure the distance between field lines at various points.
Step 6: Remove the paper and observe the pattern formed by the filings.
Step 7: Repeat the process with different shapes and sizes of magnets.
Step 8: Use a compass to determine the direction of the magnetic field.
Step 9: Record observations and compare field patterns of different magnets.
Step 10: Analyze how the shape and strength of magnets affect their field patterns.
The iron filings should align along the magnetic field lines, creating a visual map that shows the field's direction and strength. Different magnets will produce unique patterns.
Type and shape of magnet
Pattern and distribution of iron filings

Handle iron filings carefully to avoid inhalation or eye contact. Use magnets safely, keeping them away from electronic devices.
Create a large display board with photos of different magnetic field patterns.
Include a video demonstration of the experiment in action.
Explain the real-world applications of magnetic fields.
Iron filings become tiny magnets themselves and align along the field lines due to magnetic forces.
Yes, certain materials like mu-metal can block or redirect magnetic fields.
No, magnetic field strength varies based on the material and size of the magnet.
