Magnetic Field Visualization Experiment with Iron Filings and Compass #233154 (License: Personal Use)

This classic physics demonstration shows magnetic field lines using iron filings suspended in water inside a transparent bowl. A compass needle (marked 'N') rests at the bottom, while a hand-held magnet above induces alignment of the filings into curved paths from north to south pole. The dashed line indicates the field direction, illustrating how magnetic influence propagates through space.

Used in educational settings-classrooms, science museums, or online learning modules-to teach magnetism fundamentals. Matches user intent for visual explanations of magnetic fields, DIY science experiments, or curriculum-aligned physics resources.
