Magnetic Separation Experiment - Visual Demonstration of Magnetism #3656566 (License: Personal Use)

The image shows a human hand holding a red-and-blue U-shaped (horseshoe) magnet above a transparent petri dish containing a mixture of light-colored sand and small metallic iron filings. The iron filings are visibly attracted to the magnet’s poles, forming concentrated lines along the magnetic field, while the non-magnetic sand remains undisturbed. This illustrates the principle of magnetic separation used in both education and industrial applications.

This image is commonly used in educational websites, science blogs, and K-12 curriculum materials to explain magnetism, physical properties of matter, and separation techniques; it matches user intent for visual learning, lesson planning, or DIY science experiment guides.
