Bar Magnet with Iron Filings - Visualizing Magnetic Fields #3755503 (License: Personal Use)

This high-resolution image features a rectangular bar magnet, half red (marked 'N' for north pole) and half blue (marked 'S' for south pole), surrounded by fine black iron filings that form dense, branching patterns at each pole. The filings visually map the magnetic field lines, demonstrating how field strength is greatest near the poles. The clean white background enhances contrast and focus on the physical phenomenon.

Used in educational content (e.g., K-12 science lessons, university physics labs, or online STEM tutorials) to illustrate magnetic fields; matches user intent for visual explanations of magnetism, classroom resources, or science demonstration imagery.
