How Magnets Work: Visual Guide to Magnetic Fields and Attraction #3345114 (License: Personal Use)

This illustration shows a U-shaped (horseshoe) magnet with clearly marked north and south poles in orange, generating a strong magnetic field across the gap. Iron nails are attracted to both poles, visually demonstrating ferromagnetism and magnetic induction. The clean, cartoon-style rendering emphasizes core physics concepts for educational use.

Used in educational websites, STEM lesson plans, and physics explainers to illustrate magnetic attraction, polarity, and field lines; matches user intent for learning basic electromagnetism or preparing classroom visuals.
