How Magnets Attract Metal Objects - Science Illustration #3343829 (License: Personal Use)

This illustration shows a red-and-gray U-shaped (horseshoe) magnet with clearly labeled north (N) and south (S) poles. Several metallic nails are attracted and suspended across the gap, illustrating magnetic field lines and induced magnetism in ferromagnetic materials. The clean vector style emphasizes educational clarity.

Used in educational websites, science textbooks, and classroom presentations to explain magnetism, magnetic poles, and ferromagnetism. Matches user intent for visual learning about basic physics concepts.
