How Magnets Work: Visual Guide to Magnetic Attraction #172460 (License: Personal Use)

This cartoon-style illustration shows a red-and-silver U-shaped (horseshoe) magnet with its north and south poles attracting three metallic nails. The visual emphasizes how magnetic fields concentrate at the poles, enabling strong attraction of ferromagnetic materials like iron. The clean lines and bold colors make it ideal for educational diagrams explaining basic electromagnetism.

Used in K-12 science curricula, physics textbooks, and educational websites to explain magnetic fields, poles, and ferromagnetism; matches user intent for visual learning or quick conceptual reference.
