How Magnets Work: Visual Guide to Magnetic Fields and Forces #3345144 (License: Personal Use)

The image depicts a human hand securely holding a red U-shaped (horseshoe) magnet, whose poles are capped in gray to indicate north and south polarity. To the left, evenly spaced blue wavy lines represent the magnetic field extending outward from the magnet, visually conveying the concept of invisible force fields. This simplified illustration is ideal for introductory physics or STEM education.

Used in educational web pages, science blogs, or classroom resources explaining magnetism basics; matches user intent for visual learning about magnetic fields, poles, and forces.
