How Magnets Work - Visual Guide to Magnetic Fields #168255 (License: Personal Use)

This illustration depicts a classic U-shaped (horseshoe) magnet with red body and gray pole caps, visualizing the magnetic field using concentric curved lines emanating from the north and south poles. The field lines represent the direction and relative strength of the magnetic force, denser near the poles where the field is strongest. Such diagrams are foundational in physics education for demonstrating magnetic dipole behavior.

Used in educational websites, STEM lesson pages, or physics explainer articles to illustrate magnetic fields; matches user intent for learning basic electromagnetism concepts or preparing classroom visuals.
